46 COCKERELL AND COLLINGE : CHECK-LIST OF SLUGS. 



l^-^o. 



any Veronicella found in the West Indies might safely be 

 dubbed occidttiialis. I do not for a moment suppose that 

 true occidentalis is found in the Greater Antilles, or Icevis 

 {sloanii)^^ which has been confused with it, in the Lesser. 



The type of occidenta/is 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 

 to 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 



punctatissi/na, 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 timet atissiina. In fact, 



it seems highly probable that it and piinctatissinia are one 



species, as has already been suggested by Mr. Guppy 



{J. 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 incjuire whether this is not Semper's 



V. ucrulescens, already known from Venezuela. 



545. V. liicicr, Ckll. Length about 67 mm. ; breadth 23^ mm. ; 



sole, breadth 1 1 mm. ; female orifice about 38 mm. from 



head, and i| 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 hn'is 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.
