220 COCKERELL AND COLLINGE : CHECK-LIST OF SLUGS. 



any Veronicella found in the West Indies might safely be 

 dubbed occidentalis. I do not for a moment suppose that 

 true occidental is is found in the Greater Antilles, or lezvis 

 (sloanii),- 1 which has been confused with it, in the Lesser. 



The type of occidentalis was from St. Vincent, and the 

 description indicates it as brown above, with dark brown 

 points ; pale beneath, with a few brown points towards the 

 sides. Length, 65 mm.; breadth, 15 mm. 



The description, by itself, would not enable us to decide 

 about the identity of the species, but whenever specimens 

 agreeing with it are brought from St. Vincent, it will be 

 possible to record the structural character which may serve 

 :o indicate the species wherever found. 



It seems quite probable that occidentalis really does range 

 southwards to the continent. In the British Museum 

 there are specimens from British Guiana (I. Quelch) which 

 above are dark brown with black peppering, below pale 

 purplish-grey with some black spots : these might well 

 be occidentalis. Another question arises, with regard to 

 punctatissima, Semper. This species is recorded from 

 Porto Rico, St. Thomas, and Trinidad, and very likely 

 occurs in most of the Lesser Antilles. I have said above 

 that I do not suppose occidentalis to be a native of the 

 Greater Antilles, but it may extend as far as Porto Rico, 

 and have just such a distribution as punctatissima. In fact, 

 it seems highly probable that it and punctatissima are one 

 species, as has already been suggested by Mr. Guppy 

 {/. of Conch. , 1893, p. 222). Semper himself indicated 

 this possibility. Mr. Guppy, in the article quoted, records 

 only one Veronicella from Trinidad, namely occidentalis. 

 While this record is probably correct, his earlier writings 

 (Proc. Sci. Assoc. Trin., 1866; An. Mag. N. H. (3 sen), 

 vol. xvii., p. 47) seem to indicate the existence of a second 

 species, described as dark grey. It is for the Trinidad 

 naturalists to inquire whether this is not Semper's 

 V. icerutescens, already known from Venezuela. 

 545. V. incur, Ckll. Length about 67 mm. ; breadth 235 mm ; 

 sole, breadth n mm.; female orifice about 38 mm. from 

 head, and ih mm. from sole. Sole rounded posteriorly, 

 not projecting beyond body. Mantle finely fitted. Sides 

 produced, so that a transverse section of the slug would be 



-' If Prof. Cockerell thinks the term sloanii preferable to Levis he might at least set the 

 example by using it, or adhere to either the one or the other. Note 537 is very confusing.— W.E.C.
