AbstractA systematic revision of the aleocharine genus Pontomalota is presented. Pontomalota is redescribed, and two species are recognized, one of which is described as new (P. terminalia Ahn and Ashe, Type locality-Point Reyes, North Beach, California). P. californica Casey, P. nigriceps Casey, P. luctuosa Casey, and P. bakeri Bernhauer are shown to be color variants of one species and are synonymized under the name P. opaca (LeConte). A key is provided for separation of the known species of Pontomalota, and illustrations of diagnostic features are provided. The geographical body color variation of P. opaca from British Columbia to Baja California is described. In general, the body color of P. opaca varies from black in the north (Canada, Washington to N. California) to light brown in the south (S. California, Baja California) along a more or less continuous dine. Based on mouthpart structure and genitalic structure, as well as narrowly separated mesocoxal cavities and elytra shorter than pronotum, Pontomalota is hypothesized to be more closely related to tribe Phytosini than tribe Athetini. Within the Phytosini, members of Pontomalota are very similar to those of Thinusa Casey in a number of characters.

We examined the ontogenetic change of body color patterns in the laboratory-raised juveniles of six terrestrial hermit crab species, including Birgus latro, Coenobita brevimanus, C. cavipes, C. purpureus, C. rugosus, and C. violascens, which commonly occur in the southern islands, Japan. The body color patterns of coenobitid juveniles were species-specific. The diagnostic features of body color patterns enable identification of juveniles of coenobitid crab species in the wild, thereby helping to understand the precise habitats of each coenobitid species.

Oxygen Concentrations

Abstract Declining oxygen concentrations in the deep ocean, particularly in areas with pronounced oxygen minimum zones (OMZs), are a growing global concern related to global climate change. Its potential impacts on marine life remain poorly understood. A previous study suggested that the abundance of a diverse suite of mesopelagic fishes off southern California was closely linked to trends in midwater oxygen concentration. This study expands the spatial and temporal scale of that analysis to examine how mesopelagic fishes are responding to declining oxygen levels in the California Current (CC) off central, southern, and Baja California. Several warm-water mesopelagic species, apparently adapted to the shallower, more intense OMZ off Baja California, are shown to be increasing despite declining midwater oxygen concentrations and becoming increasingly dominant, initially off Baja California and subsequently in the CC region to the north. Their increased abundance is associated with warming near-surface ocean temperature, the warm phase of the Pacific Decadal oscillation and Multivariate El Niño-Southern Oscillation Index, and the increased flux of Pacific Equatorial Water into the southern CC.

Fractures in Late Cretaceous to Late Pleistocene sediments in Saskatchewan, eastern Montana, and western North Dakota form two vertical, orthogonal sets trending northeast–southwest and northwest–southeast. The pattern is consistent, regardless of rock type or age (except for concretionary sandstone). Both sets appear to be extensional in origin and are similar in character to joints in Alberta. Modem stream valleys also trend in the same two dominant directions and may be controlled by the underlying fractures.Elevation variations on the sub-Mannville (Early Cretaceous) unconformity form a rectilinear pattern also parallel to the fracture sets, suggesting that fracturing was initiated at least as early as Late Jurassic. It may have begun earlier, but there are insufficient data at present to extend the time of initiation.We interpret the fractures as the result of vertical uplift together with plate motion: the westward drift of North America. The northeast–southwest-directed maximum principal horizontal stress of the midcontinent stress field is generated by viscous drag effects between the North American plate and the mantle. Vertical uplift, erosion, or both together produce a horizontal tensile state in near-surface materials, and with the addition of a directed horizontal stress through plate motion, vertical tension cracks are generated parallel to that horizontal stress (northeast–southwest). Nearly instantaneous elastic rebound results in the production of second-order joints (northwest–southeast) perpendicular to the first. In this manner, the body of rock is being subjected with time to complex alternation of northeast–southwest and northwest–southeast horizontal stresses, resulting in the continuous and contemporaneous production of two perpendicular extensional joint sets.

AbstractAn isolated burial was excavated from the bank of a tributary of Gordon Creek, Roosevelt National Forest, northern Colorado. A preliminary report was prepared (D. Anderson 1966, 1967) but further analysis of the skeletal material and newly obtained cultural information add significantly to the documentation of the burial.The body of a woman, aged 25-30 years, was given primary interment in a pit coated with red ocher. The body was placed on its left side with the head to the north, was tightly flexed, and was also coated with red ocher. Burial accompaniments include a large precussion flaked biface or preform, a small biface used as a scraping tool, a hammerstone, an end scraper, a preform with fire pocks, cut and incised animal ribs, and a perforated elk incisor. A radiocarbon assay of bone material from the left ilium produced an age of 9700± 250 radiocarbon years: 7750 B.C. (GX-0530).No indications of habitation which might be associated with the burial were located in its immediate vicinity.A reconstruction of the burial ritual is attempted, and the skeletal remains are compared to other early human remains from North America.A summary of this paper was given at the 34th Annual Meeting of the Society for American Archaeology, May 3, 1969, in Milwaukee, Wisconsin.

The Press

<p>The press was at the centre of the reform of the meaning of insanity, during its evolution from an equivocal eighteenth-century concept of melancholia to a medicalised Victorian notion of ‘lunacy’. During the late Georgian era newspapers provided a public forum for the opinion of newly emerging psychiatric practitioners and fostered the fears and concerns about mental illness and its supposed increase. The press was also the main source of news on crime, providing readers with reports on criminal insanity and suicide. In the first half of the nineteenth century, newspaper contents included official legal reports, as well as editorial commentary and excerpts from other publications, and newspaper articles can rarely be traced to one single author. Historians of British insanity avoid consulting periodical literature, choosing to use asylum records and coroners’ reports, as these sources are more straightforward than newspapers. However, Rab Houston’s recent study of the coverage of suicide in the north of Britain shows that the provincial press has been unjustly overlooked and can offer the material for a unique social analysis. Asylum records and coroners’ records do not contain the same detail provided in the press. Newspaper commentary can arguably reveal contemporary attitudes towards insanity and, moreover, sources such as asylum records only deal with the lower-class patients, as the middle- and upper-class insane were usually privately detained.  This thesis examines the press coverage of insanity in Leeds newspapers, and expands on previous research by looking at the way insanity was portrayed in the two most popular publications in the industrial region of Yorkshire: the Leeds Intelligencer and the Leeds Mercury. Chapter one focuses on legal cases that featured a verdict of insanity and explores the language used by the press in the reports of, mainly, violent domestic crime. Chapter two looks at reports of suicide and considers how contemporary views on financial and moral despondency influenced the portrayal of self-murder. Chapter three considers editorial articles that cannot be described as either crime or suicide reports. This chapter uncovers the presence of surprisingly humorous and entertaining articles on insanity found in editorials and the ‘Miscellany’ sections of the newspapers. Ultimately, this thesis argues that the reportage of insanity in the Leeds press was sensational, moralistic and selectively sympathetic; furthermore, such portrayal of insanity was reinforced throughout the body of the paper. Leeds newspapers segregated the insane by adopting a moralising tone and by choosing to use class-specific language towards the insane of different social ranks.</p>

No description of the young of this species seems to exist, with the exception of that given by Emery (1) of some examples from Naples.The specimens here described were captured at Newquay, on the north coast of Cornwall, in September, 1898, and have been preserved in formol. They were caught in sandy pools surrounding or surrounded by rocks in the shelter of which they seemed to be fond of lying. When disturbed they darted with considerable rapidity from place to place, and in doing so were seemingly assisted by the large pectoral fins which were carried nearly at right angles to the body by the fish when at rest.
