The montane pitvipers (Cerrophidion spp.) consist of five recognized species that disjunctly occupy high elevational habitats from southern Mexico to western Panama. However, two of these species were recently delineated, leaving previously published natural history data on Cerrophidionoutdated and in need of a re-examination. To gain more information, we investigated the stomach contents of Cerrophidion specimens housed in the University of Illinois Museum of Natural History Herpetology Collection (UIMNH) and report our findings. We also compiled lists of all known prey items and present a comprehensive dietary synopsis for each species of Cerrophidion according to recent taxonomic changes. These efforts unearthed eleven previously undocumented prey items for three of the species.

The Venezuelan forest pitviper (Bothrops medusa) is an endangered viperid endemic to the central range of the Cordillera de la Costa in Venezuela. Little is known regarding its natural history. We examined the stomach contents of museum specimens housed in the University of Illinois Museum of Natural History Herpetology Collection and report the first prey items for the species. The arboreal habits of both prey items support the notion that B. medusa may be semi-arboreal. This exposes the need for further studies on this rare viperid and showcases the value of natural history collections for studying endangered species.

Prey Items

The Mexican small-headed rattlesnake (Crotalus intermedius) is composed of three recognized subspecies that occur disjunctly in the central and southern highlands of Mexico. Only four species-specific prey items are reported in the literature for C. intermedius at present. To gain further insights, we dissected museum specimens housed in the University of Illinois Museum of Natural History Herpetology Collection for stomach contents and report the prey items discovered. Of the 23 specimens examined, seven contained prey, all of which were lizards of the genus Sceloporus. As a result, we report two novel prey to the known dietary breadth of C. intermedius. Furthermore, our findings, in conjunction with published literature, suggest that Sceloporus spp. are the predominant food source of C. intermedius. Due to this apparent diet specialization, the status of C. intermedius likely depends heavily on the persistence of prey populations, and for this reason, improving natural history knowledge will be vital for informing conservation efforts.

The present paper has been prepared in the course of work at the University of Illinois for the degree of master of science in zoology. In addition to extensive collections of Entomostraca made at the Biological Station of the University of Illinois, situated at Havana, on the Illinois River, I have been able, through the kindness of Dr. S. A. Forbes, to examine all the accumulations in this group made by the Illinois State Laboratoryof Natural History during the last twenty years,and covering a territory little less than continental.

Since there is currently a lack of data on the natural history and feeding ecology of Odorrana chapaensis, which was listed in the IUCN Red List (2019), we herein provided the feeding ecology of this amphibian species is virtually lacking. We herein provide data about the diet of O. chapaensis based on the results of our field work in Ngoc Chien Commune, Muong La District and Xim Vang Commune, Bac Yen District, Son La Province, Vietnam. We used the stomach-flushing method to obtain the stomach contents of 85 individuals at two survey sites. A total of 20 prey categories with 334 items, comprising 299 items of invertebrates and 35 unidentified items, were found in the stomachs of O. chapaensis. The dominant prey items of O. chapaensis were Araneae, Polydesmida, insect larvae, Blattodea, Coleoptera, Dermaptera, Lepidoptera, Hymenoptera, and Orthoptera. The importance index for these categories ranged from 3.5% to 32.5%. Coleoptera was the category with the highest frequency of prey items; its representatives were found in 45 stomaches.

We revisit the distribution and natural history data of Tachymenis chilensis chilensis (Schlegel, 1837) in Argentina based on compiled and novel records, extending its northern and southern distribution from the previously known localities in Argentina. We recorded two prey items in Argentinean populations: Rhinella rubropunctata, reported for the first time, and Liolaemus pictus. Tachymenis c. chilensis is mainly found in forested habitats, generally near wetlands with abundant populations of amphibians. The latitudinal range occupied by T. c. chilensis in Argentina is similar to that in Chile, but its northern distribution limit reaches the lowest latitudes in Chile. This is probably due to the higher humidity levels in the western slopes of the Andes and the barrier effect of the highest mountain ranges in this area.

In 1927 T. H. Frison published a list of all the insect types in the collections of the Illinois Natural History Survey and the University of Illinois and the Bolter collection. This list contained 1,067 primary types. Type-specimens in the University of Illinois have subsequently been transferred to the collection of the Illinois Natural History Survey. In the past 50 years 2,113 primary types have been added to the Survey's collection, primarily through the systematic research of T. H. Frison in Plecoptera and Hymenoptera; H. H. Ross in Trichoptera, Plecoptera, Homoptera, and Hymenoptera; H. B. Mills in Collembola; and L. J. Stannard, Jr., in Thysanoptera. The acquisitions of the personal collections of J. W. Folsom in Collembola and C. A. Robertson in Hymenoptera added numerous primary types to the Survey's collections. In addition, several active workers have periodically, or occasionally, deposited their types in the Survey's permanent collection upon completion of specific revisionary studies. Recently, Gerdes (1977) and Mari Mutt (1978) have published lists of all of the types of Thysanoptera and Collembola, respectively, in the Natural History Survey collection. In this list only primary types currently located in or on loan from the Illinois Natural History Survey collection are listed along with the original citation for each species. The literature citation for the designation of ach neotype and lectotype is also cited. To clarify the type designation within the bees of the Robertson collection, lectotype specimens have been designated by W. E. LaBerge for those species not previously designated in the literature. The genera under which the species are listed are those under which they were originally described. Where possible the sex of each type is given. The term syntype is used in the sense of Article 73c of the International Code of Zoological Nomenclature (1964) and replaces the term cotype used by Frison (1927). For simplicity, the within each order alphabetically, the genera are arranged alphabetically within each family, and the species are arranged alphabetically within each genus.

Excavations carried on in 1931 under the University of Illinois archaeological program were directed by A. R. Kelly. One of the small mounds explored during the spring of that year was excavated by W. V. Kinietz. It was called the Box Elder Mound and was located near the town of Science, in Starved Rock State Park near Utica, La Salle County, Illinois.During the summer of 1935 I was permitted by the late F. C. Baker, then Curator of the Museum of Natural History of the University of Illinois, to study and describe this material. The vessels to be described below are a part of the collections of the University of Illinois.
