AETHEOPOD PATINA OF THE WEST INDIES. 521 



seen without interruption ; the ventral surface is pale, and varies 

 from fawn- to flesh-coloured. One specimen, which seems to 

 have so far suffered less than the others from the action of 

 the spirit, has the dorsal surface nearly black and the ventral 

 distinctly flesh-coloured ; the antennse are rather darker than the 

 rest of the dorsal surface ; the legs are externally the same colour 

 as the dorsal surface, and internally pale like the ventral. 



The principal papillce vary in form according as they are 

 lengthened or contracted ; when contracted, as on the dorsal 

 surface of the largest specimen from St. Vincent, they are circular 

 at the base and rounded at the summit, without any visible distal 

 portion ; when lengthened, the basal portion becomes narrower 

 and more cylindrical, and a distal portion, tipped with one, two, 

 or very rarely three set^, projects from its summit, the whole 

 papilla then resembling in appearance a short candle-end in a 

 cylindrical candle-stick ; sometimes the distal portion is expanded 

 at its apex. 



Blades of the jaw seem to be like those of the Caraccas species 

 described by Sedgwick; thus the outer has a single tooth at the 

 base of the fang, while the inner has a single very similar tooth 

 at the base of the fang ; and this is followed by a series of seven 

 subequal but much smaller teeth. 



Legs vary in number from 29 to 34 pairs ; there are two 

 papillse on the anterior aspect of the feet : the claws are lightly 

 curved ; those of the last pairs are smaller than those that precede 

 them, and have two instead of four pads. Some of the posterior 

 legs in the male are furnished with one or two white tubercles, 

 the distribution of which in the posterior six pairs in one example 

 is as follows :— 24th 2-0; 25th 1-1; 26th 2-1; 27th 1-1 ; 28th 

 0-0 ; 29th 0-0. 



Eemale larger than male, with 33 or 34 pairs of legs ; male with 

 29 or 30 pairs. 



Measurements of largest specimens : female, length 44 mm., 

 width 6 mm. ; male, length 26 mm., width 4*5 mm. 



Locality. St. Vincent {H. H. Smith). 



Of this species I have seen six specimens : four females, two 

 having 34 and two 33 pairs of legs, and two males, one with 29. 

 the other with 30 pairs of legs. 



"With the first set of this species sent by Mr. Smith is the 

 following note: "Eare in rotten wood and decaying leaves."
