Bergh, R. — (Jpisthobranches provenant des Campagnes du yacht 1' Hirondelle. 

 Resultats des Camp. Sci. accomplis sur son yacht par Albeit I er ., Prince 

 Souverain de Monaco, Fasc. iv., pp. 1-40, plates i.-iv. , Monaco, 1893. 

 Prof. R. Bergh here deals in his usual thorough manner with the Opistho- 

 branchs collected during the cruise in the Atlantic of the Prince of Monaco's 

 yacht " Hirondelle." Three species are new to science, and one of these is made 

 the type of a new genus Pleurobranchillus. The following is the complete list : — 

 Cratena fructuosa, n.sp., Fiona marina, Forsk., Scyllcea pelagicd, L., Euplocamus 

 atlanticus, n.sp., Doriopsis limbata, Cuv., Pleurobranchus plumula, Mont., 

 P. aurantiacus, Risso, Pleurobranchillus morosus, gen. et sp. nov. , Marsenia 

 (Lamellaria) perspicua, L. The three first species were taken at the surface 

 among Sargasso, and, in the case of Fiona, on Ianthina and wreckage ; the rest 

 came from sandy bottoms varying in depth from 130 to 189 metres. The new 

 genus (? sub-genus) Pleurobranchillus agrees with Pleurobranck&a in every 

 character of importance, but approaches Pleurobranchtts in the position of the 

 anus and genital papilla and in the degree of ramification of the ptyaline gland. 

 The foot in the new genus appears not to exceed the mantle in width ; so that 

 Pleurobranchillus seems to be related to Pleurobranchcea in much the same way as 

 is Pleurobranchus to Oscanius. It is to be regretted, however, that Bergh does not 

 include among his numerous figures a sketch of the external form of P. morosus. 

 In addition to the type species, Bergh refers P. brockii, Bgh. (from the Indian 

 Ocean) to the new genus. — W. G.

 Journ. de Conchyl., 1892, pp. 279-92, pi. iv. 

 In commencing these studies, M. Crosse writes (a) on the genus Hungerfordia 

 (a remarkable form of Palaina from the Pelew Islands with a single species) ; 

 (l>) On the new genus Geothauma, proposed for Opisthostoma grandispinosum, 

 G. A., from Borneo ; (c) On Hcndeia and other neighbouring forms, intermediate 

 between Helicina and Proserpina ; (d) On the genus Bathybembix, proposed for 

 Bembix, Wats, preoccupied with a list of species known. (See Smith, E. A. ). 



Hedley, C. — Schizoglossa : a new genus of carnivorous Snails. Proc. Linn. Soc. 

 N.S.W., vii., pp. 387-91, pis. ix.-x. 

 A new genus for Datidcbardia noviseelandica, Pfr. The description is : "Shell 

 worn on the tail, incapable of containing the body, and reduced to the function 

 of a shield to the lungs and heart, rudimentary, paucispiral, nacreous within, 

 columella excavated in a pit for the reception of the shell muscle. Animal lacking 

 rachidian teeth." Very insufficient grounds for a new genus, and the more 

 surprising coming from an anatomist of Mr. Hedley's standing. — W.E.C.

 The new species are Macularia pantocratoris, Brom., Campylcea pterolaka,

Von Mollendorff proposes a new genus Hcmiglypta, with type H. 

 blainvilleana, Lea, in place of Hemiplecta, Alb. , which originally included species 

 of Hcmitrichia and Rhysota, and whose type species {hnmphreysiana, Lea), as 

 proposed by von. Martens is a Rhvsota. Besides the type, nine species are 

 enumerated from the Philippines, viz. monssoni, Semp., sempcri, Mf., conncctens, 

 Mf. , mayonensis, Hid., scmiglobosa, Pfr. globosa, Semp., infraslriata, Mf., 

 cuvioiana, Lea, microglypta, Mf.
