ARISTELLIGER PRAESIGNIS (Hallowell) 



Hcmidactyhis pracsignis Hallowell, Proc. Acad. Nat. Sci. Philadelphia, 1856, 

 p. 222. 



lliree geckos of this species were taken on Six Hill Cay off South 

 Caicos on August 3, 1930, now U.S.N.M. nos. 81444-6. They do not 

 differ essentially from the 16 Jamaican pracsignis in the national 

 collection. All the Caicos lizards have eight upper labials and seven 

 lower labials. Their subdigital lamellae are really 20 to 21 in number, 

 although only 13 to 16 of these are enlarged beyond the width of the 

 surrounding granules. The largest specimen measures 72 mm from 

 snout to beginning of tail ; the tail itself has been partly reproduced, 

 but now measures 86 mm. 



These lizards were found by turning over rocks.

SPHAERODACTYLUS BARTSCHI, n. sp. 



Diagnosis. — Dorsals keeled, imbricate, no differentiated middorsal 

 zone ; about nine dorsals in the standard distance between center of eye 

 and tip of snout ; lateral grooves more or less apparent on the rostral ; 

 faintly or distinctly spotted on the posterior part of body and on tail ; 

 sometimes a light dark-bordered stripe on each flank extending onto 

 the tail ; adult size rather small. 



Type. — U.S.N.M. no. 81759, an adult male from Little Cayman 

 Island, taken September 12-13, 1930. 



Description of the type. — Snout moderately long but not very 

 acutely pointed, its length two and one-half times the diameter of the 

 eye ; eye slightly nearer ear than tip of snout ; rostral moderate, with a 

 long median cleft behind, with merely a trace of lateral crescentic 

 grooves ; nostril between rostral, first supralabial, two postnasals (the 

 upper the smaller) and a large supranasal which is separated from its
