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



(4) Australian Region. 



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



New Caledonia . 1 „ 



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

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

 I hope to write at some future time *. 



Vaginulince. 



While the Veronicellince have a ribhed jaw and quadrate marginal 

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

 the two subfamilies diflPer from one another much as the Arionidcf 

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

 but 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 Vagimdidce are carnivorous, as from their structure they 

 should be. 



Under Vaginulince are three genera: — Rathousia, 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, Veronicella 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^. 



A RioNiDiE. — Pkilomgcince. 



Consists of a single genus Limacella, Blainv. (Pkilomycus, Raf.), 

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

 1890. The distribution of iz»2aceZ/a is very remarkable. It occurs 

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

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

 the only intermediate localities being Japan and the Sandw^ich Is. 



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

 in which inany new species are indicated ; I have altered the statistics above bo 

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

 Eeisen im Arch. Phil. 1885. 



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

 not actually propose a genus Vaginulns ; indeed he described (Journ. As. Soe. 

 Bengal, 1873) a species from Penang vrith the characters of this genus under 

 the head of VeronicdJa hirmanica. Vagimdtis, as here understood, vras 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 tlie 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 Aiopos, and that the Huon Gulf one (ap' 

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