Closely resembles C. Sheppardi^ but is of a deep blue 

 colour, the legs being also blue. Besides the difference in 

 colour, this species is distinguished by the punctuation of the 

 elytra, which is as strong as in C. Sheppardi but less close.

L. — Remarks on Dr. A. Sfrauch''s Catalogue of the Geckos 

 in the Zoological Museum of the Imperial Academy of St. 

 Petershurg *. By G. A. BOULENGER. 



This important memoir contains an enumeration of all the 

 Geckoid Lizards (inclusive of the Eublepharidse and Uro- 

 platidse, which are united with the Geclconidaj) in the St. 

 Petersburg Museum. We learn that 122 species are repre- 

 sented in that collection by upwards of 637 specimens. A 

 dichotomical key is given of all the genera, but only such 

 species as are new or imperfectly known are described. The 

 author has not adopted tlie sequence followed in the British- 

 Museum Catalogue, in which the series of genera commences 

 with the least specialized forms, i. e. those in which the digits 

 are not dilated; he prefers commencing with the most 

 " typical " forms, in which the Geckoid character is most 

 highly developed. Two new genera are established, viz. 

 Cnemaspis, allied to Gonatodes, for a new species from Pulo 

 Condor, and Ptenodoctylus, allied to Stenodactylus^ for a 

 Turkestan form, P. Eversmanni, Wiegm., which had never 

 been properly described before. Twelve other new species 

 are established, on three of which 1 have to offer some 

 remarks. 



First with respect to the new Gehyra^ G. Fischeri^ from 

 Ternate ; I am inclined to think that this is a young male 

 of the same form that I described, almost simultaneously, 

 from an adult female from Morty, and named G. marginata. 

 The volume in which I published its description having been
