COCKERELL AND COLLINGE : CHECK-LIST OF SLU(;S. 47 



somewhat fusiform in oulline. Colour, above dull ratlur 

 dark olivaceous, below (including sole) dull reddish-brown. 

 Habitat : Fond St. Jacques, St. Lucia. In British Museum. 

 This appears to be a very well-marked species, so 

 I venture to describe it, the anatomy being unknown. 



Simper has doubtfully referred to occidentalii a slug from 

 St. Thomas, which presents some resemblance to liiciie. 

 The position of the female orifice is almost precisely the 

 same ; and the whitish colour, without markings seems to 

 ally it to luciiB. However, in Simper's slug the breadth, as 

 compared with the length — the breadth of the sole, and 

 the total length — all differ from lucice. Thus: — V. lucice 

 has the breadth '34 and the breadth of sole '16 of total 

 length. In Semper's slug the measurements are '26 and 

 •08 of total length. 



In the British Museum there is a small species from 

 Dominica, black with the head and sole brown. It seems 

 to be a new species allied to langsdorfi, but I hold back 

 the description in the hope of further specimens being 

 collected, so that dissections can be made. 

 550. V. solea. It is doubtful whether this is a widely distributed 

 and variable species, or whether there is a group of distinct 

 species closely allied to it. Some such species have been 

 separated, and must for the present be held valid, namely, 

 V. tuberculosa, V. maridtiita, and V. multicoior. For 

 figures of these slugs see Mrs. Ciray, Fig. Moll. A/iii/i., 

 1859, pi. 278, f 2 (or D'Orb., Voy. Amer. Mer., t. 21. 

 f 3-4), Bui. Soc. Zool.^ France, 1889 ; Jahrbitch </. D. Mai. 

 Ges., 1885, Taf 2, 4 ,and Semper's work. 

 576. V. andcnsis. Perhaps identical with liniayana. 

 584. V. nigra. May be identical with ^s,7?)7'. 

 588-589. V. kreidelii and telescopium. These are supposed to be 

 American. 



In the list I have given the species of Veronicella in groups 



according to locality, but a better classification of them is to 



be desired. Dr. Simroth has proposed three groups, thus : — 



((?) Acrocaulier. Penis perforate at the point ; eciua- 



torial, e.g., V. sloanii. 

 (b) Phyllocaulier. Group of V. tuberculosa and allies; 



neo-tropical. 

 {c) Pleurocaulier. Penis laterally perforated ; Asiatic 

 and African, e.g., V. iiiaculata.
