COTRIBUTIONS TO COCCIDOLOGY.—I

Dactylopius sorghiellus, Forbes. Syn. D. Kingii, Ckll.Dr. S. A. Forbes has kindly sent me the type material of this species, which I have examined with much interest. The material studied consisted of 4 specimens. As is usual with these subterranean forms the antennæ are quite variable, both in the number of segments and their relative length.Only two of the antennæ of the 4 specimens were 8 jointed, the others being 7-jointed, and some plainly aborted. After careful measurement and study, I conclude that the forms described by Cockerell in Science-Gossip, Feb., 1897, p. 240, as D. Kingii, must be referred to this species.

One New Species

Species of Marphysa belonging to the Aenea-group have compound falcigers as the subacicular chaetae along the entire body. Around 30 species belong to this group, among these, two have originally been described based on Australian specimens, M. bifurcata and M. sessilobranchiata. Here, we redescribe both species based on type and non-type material and describe a species new to science, M. pseudosessiloa n. sp., including intraspecific variation. Informative features for the identification of these species are relative length of prostomial appendages in relation to prostomium, shape of notopodial cirri, left MxIV plate, left and right MxIV attachment lamellae and placement of branchial stem. A taxonomic key to species of Marphysa currently reported from Australia is also provided.

AbstractA collection of Haemogamasus nidi Michael, 1892 and H. nidiformis Bregetova, 1955 from Scandinavia and NE USSR was compared with type material. Differences in the number of setae and the relative length and area of the genito-ventral shield can be used to seperate females of the two species.

Three New Species ◽

Number Of Segments

Capitellids of the genus Scyphoproctus are most readily identified by the distinctive pygidial region, generally consisting of a number of segments fused with the pygidium, forming a weakly or well-developed anal plaque. To date, there are 17 valid species, however, only one species has been previously recorded in Brazil. The aim of this study was to investigate the diversity of the genus occurring along the Northeast and Southeast coasts and sublittoral areas of Brazil. Three new species have been found in samples collected in a variety of habitats and depths, Scyphoproctus paivai sp. nov., S. profundus sp. nov., and S. robustus sp. nov. The new species are herein described and compared to other species of the genus and type material of two additional species are re-described, Scyphoproctus oculatus Reish, 1959 and S. pseudoarmatus (Silva 1965). The genus Heteromastides Augener, 1914 is herein relocated in Scyphoproctus Gravier, 1904 and the previous species Heteromastides platyproctus Pillai, 1961 (junior homonym) renamed as Scyphoproctus telesphorei n. nov. after the species author Telesphore Gottfried Pillai, because there is already a species named Scyphoproctus platyproctus Jones, 1961 (senior homonym). A taxonomic key of the valid and new species is also given.

Stratigraphic Position

Pseudoclypeina? crnogorica was first described in 1972 from the Lower, Cretaceous limestone of the Njegos Mt. area, Montenegro, Dinaric Carbonate Platform. It differs from other species of the genus Pseudoclypeina by its calcification pattern, the shape and relative length of the first and second order laterals, and by the presence in the type-material (a thin section containing the holotype) of sections standing for the sterile portion of the thallus. This is why in this paper, the generic name is left in open nomenclature. On this occasion the species, whose presence is also reported from southern Iran, is re-described and better illustrated, based on material originating from other outcrops in Montenegro. The stratigraphic position is reviewed as well. Pseudoclypeina? crnogorica occurs in shallow water inner platform facies of early Neocomian age, along with Selliporella neocomiensis.

Different Diameters

The effect of the position of lines on length estimation was investigated. 40 5-yr.-olds were asked to compare the two arms of an L-shaped figure presented inside circular frames of different diameters. For each figure one of the arms was on the axis, that is, the diameter, and the other arm was perpendicular to that axis. In making perceptual judgments about the relative length of two lines the children tended to describe the on-axis line as longer than the off-axis line. This illusion which, presumably, reflects a perceptual force induced by the characteristics of the structural pattern, supports the context model of visual anomalies.

Porphyrin Macrocycles

The synthesis of new graphene-type materials (via polymerization of porphyrin macrocycles) through a simple chemical synthetic pathway (at RT) has been demonstrated. This newly synthesized material can be dispersed in water with an average sheet size of few microns and with single layer thickness. As the porphyrin contains four inner ring nitrogen atoms thus the presented polymeric material will be close analogous of N-doped graphene. Porphyrin as the key component to synthesize layered graphene type continuous 2D structure has never been attempted before.

The fauna of Gryllomorphinae of Turkey is reviewed. Sixteen species and subspecies are established. Ovaliptila anamur sp. nov., O. anitli sp. nov., O. alanya sp. nov., O. alanya proxima subsp. nov., O. alara sp. nov., O. teke sp. nov., O. ibrahimi sp. nov., Glandulosa borisi sp. nov. and Gryllomorpha dalmatina minutissima subsp. nov. are described. Ovaliptila beroni (Popov, 1975), Glandulosa kinzelbachi Harz, 1979, G. harzi Gorochov, 1996 and Gryllomorpha Antalya Gorochov, 2009 are briefly characterized based on the type material. Ovaliptila buresi Mařan, 1958 is indicated as a rather widely distributed species in the western part of Anatolia (but not in the southern coast of this peninsula). Gryllomorpha dalmatina pieperi Harz, 1979, G. miramae Medvedev, 1933 and the nominotypical subspecies of G. miramae are recorded from Turkey for the first time, but both subspecies remain open to question.

The presented experimental and digital examinations of a two-dimensional turbulent free jet are a first phase of in the study of the Coandă effect and its hysteresis. Additionally, basing on theoretical analyses, selected results for a turbulent jest have been also mentioned, considering theoretical assumptions for the wall layer. As the result, on the basis of experimental, digital, and analytical methods, a review of characteristic jet properties has been prepared, which includes a jet spreading ratio, its cross and longitudinal sections, and turbulence level. The jet spreading radio has been expressed as a non-linear function of the x : b relative length.
