COCK.ERELL AND COLLINGE : CHECK-LIST OF SLUGS. 22 1 



somewhat fusiform in outline. Colour, above dull rather 

 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 occidcntalis a slug from 

 St. Thomas, which presents some resemblance to lucice. 

 The position of the female orifice is almost precisely the 

 same ; and the whitish colour, without markings seems to 

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

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

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

 has the breadth "34 and the breadth of sole - i6 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. marianita, and V. multicolor. For 

 figures of these slugs see Mrs. Gray, Fig. Moll. Anim., 

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

 f. 3-4), Bui. Soc. Zoo/., France, 1889 ; Jahrbuch d. D. Mai. 

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

 576. V. andeusis. Perhaps identical with limayana. 

 584. /". nigra. May be identical with gayi. 

 588-5 89. 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 : — 

 (a) Acrocaulier. Penis perforate at the point ; equa- 

 torial, e.g., V. sloanii. 

 (/>) Phyllocaulier. Group of J', tuberculosa and allies; 



neo-tropical. 

 (c) Pleurocaulier. Penis laterally perforated ; Asiatic 

 and African, e.g., V. maculata.
