220 MR. T. D. A. COCKEBELL ON THE [ApT. 7, 



(4) Australian Region. 



New Guinea . . 2 species. Queensland . . 3 species. 



New Caledonia . 1 „ 



There are also specimens from Port Elizabeth, S. Africa, Panama, 

 Honduras, and St. Lucia in the British Museum collection, of which 

 I hope to write at some future time ^ 



Vaginuliufje . 



While the Veronicellince have a ribbed jaw and quadrate marginal 

 teeth, the Vaginulince have no jaw and the teeth all aculeate. Thus 

 the two subfamilies differ from one another much as the Arionida- 

 differ from the Testacellidcs, so far as these particulars are concerned, 

 l)ut in other respects they seem so closely allied that they may be 

 united under a single family. It would be interesting to ascertain 

 whether the VaginulidcB are carnivorous, as from their structure they 

 should be. 



Under Vaginulince are three genera: — Rathonsia, Heude, with three 

 species, from China ; Vaginulus, " Stol." ", Cochin China and the 

 Malay Peninsula : and Atopos, Simroth, found in Amboina and 

 Mindanao, and apparently also in New Guinea and Queensland. 

 Perhaps these three genera will not all prove distinct, but I have 

 not made any critical examination of them myself. Superficially, 

 the species of Vaginulus may be known by their subcylindrical shape 

 and broad sole, Vei-onicella being flattish with a narrow sole. A 

 species which 1 refer to Vaginulus is in the British Museum, from 

 Penang ; and an Atopos (or something closely allied) from Huon 

 Gulf, New Guinea. This last is probably the V. prismatica, T,-Can., 

 which is, I suppose, a species of Atopos ^ 



Arionid^. — Philomycince, 



Consists of a single genus Limacella, Blainv. {Philomycus, B-af.), 

 which I have treated in some detail in Ann. Mag. N. H. for Nov. 

 1890. The distribution oi Limacella is very remarkable. It occurs 

 in Central America and Eastern North xlraerica, but not at all west 

 of the Eockies. It reappears in the Chino-Malay and Indian regions, 

 the only intermediate localities being Japan and the Sandwich Is. 



^ Dr. Simroth has just published a paper (see Bes. Abdr. nat. Ges. Leipzig) 

 in which many new species are indicated ; I have altered the statistics above so 

 as to include these. For the anatomy of many species of this genus see Semper, 

 Eeisen im Arch. Phil. 1885. 



2 Stoliczka is quoted as authority for this genus as here limited, but he did 

 not actually propose a genus Vagmulus ; indeed he described (Journ. As. Soc. 

 Bengal, 1873) a speciiis from Penang with the characters of this genus undei- 

 the head of Vewnicdla Urmanica. Faginukis, as here understood, was defined 

 by W. G. Binney in 1879. 



^ Since this was written, I have received a letter from Dr. Simroth, to 

 whom I had sent some particulars of the Penang and Huon Gulf specimens. 

 He thinks that the Penang one (which is certainly a species of Vaginulus^ 

 W. G. Binney) is congeneric with his Atopos, and that the Huon Gulf one (ap_' 

 parently V. prismatica, T.-Can.) probably represents a new genus or subgenus."
