limestone fences and so has wide distribution. It breaks up into a 

 number of subspecies, which are briefly characterized in the adjoin- 

 ing key. 



Field notes on the coloration of the animals of a number of these 

 various races were taken by Bartsch in 1928 and are here reproduced. 



Chondropoma {ChondTopoma) pictum pictum 



Fundador, Station 2, bluffs of Canimar River below ferry, right 

 side, July 20, 1928. 



Animal short, forehead with many short streaks and dots of brown ; 

 body behind forehead ashy gray. Ring about base of tentacles pale 

 buff. Tip of mouth a little paler than ring. Tentacles buff below, 

 grayish brown above. The bottom color extends up on the sides. 

 Sides of body and sole of foot ashy gray. Sole of foot deeply medi- 

 ally cleft, locomotion of two sides alternate. 



Chondropoma {Chondropoma) pictum mahogani 



Paradones at Rifle range, 2 miles south of Limonar, July 23, 1928. 



Animal short, of general buffy tinge, with a dark band across the 

 forehead immediately in front of the tentacles; behind the tentacles 

 it is streaked and spotted with brownish, which gives this part a 

 somewhat marbled effect. Behind this the body is flesh-color, with a 

 pinkish-buff flush, which is also the color of the sides of the body 

 above the foot. Sides of foot pale ashy; sole also ashy but a little 

 paler than the sides, deeply medially cleft. Tentacles buff, with a 

 median dorsal streak of brownish, or in some specimens grayish. 



Chondropoma {Chondropoma) pictum yumeriense 



Vista Alegre, July 19, 1928. 



Animal short, forehead with many wark short streaks and dots of 

 brown. Edge of snout smoky flesh-color. Tentacles with the base 

 huffish flesh-color, slightly orange beneath, brownish above. Sides of 

 body smoky gray ; sole a little paler. 



This in coloration seems intermediate between yucayuni and pictum 

 from Fundador. 



Chondropoma {Chondropoma) pictum celsum 



From Station 19, El Palenque, Matanzas, July 21, 1928. 



Animal short with the forehead flesh-color, marked by numerous 

 small, elongate, brownish spots; body behind the forehead soiled 

 flesh-color. Ring about the base of tentacles buff-orange, which is 

 also the color of the tentacles excepting an inner gray core. Tip 

 of tentacles brownish orange. Sides of the body ashy, darkest toward
