On the Local Races of some Canarian Lizards. G7 



Gamhusia 7/uca(ana, sp. n. 



Depth of body 2^ to 3 in the length, lengtli of head 3_^ to 

 3^. Diameter of eye 3^ to 3^ in the length of head, inter- 

 oibital width about 2. 28 scales in a longitudinal series. 

 Dorsal 7-9; origin above posterior end of base of anal ( ? ), 

 equidistant from head and base of caudal ((J) or nearer 

 caudal ( ? ); longest rays i length of head. Anal 11 ; first 

 and second branched rays somewhat produced, free edge 

 emarginate ( $ ). Pectoral | length of head or more, 

 extending to above origin of anal. Caudal rounded or sub- 

 truncate. Least depth of caudal peduncle | length of head. 

 A daik bar below eye ; series of small dark spots along rows 

 of scales on upper part of body ; dorsal and caudal fins 

 S])otted. 



Progreso, Yucatan. 



Four specimens (2 ^ , 2 ? ) up to 50 mm. in total length. 



This species is closely related to G. nicaragiiensis, but has 

 a larger head and the dorsal fin further forward. The intro- 

 niittent organ differs considerably in structure from that of 

 males of G. nicaraguensis from Southern Mexico (cf. P. Z, S. 

 1913, p. 983, fig. 168, A) ; males from Lake Nicaragua have 

 not yet been described. 



XL — Preliminary Notes on the Local Races of some 

 Canarian Lizards. By C^SAR R. BoETTGEK and 

 LOKENZ M ULLER. 



The material on which the following notes are based was 

 collected by myself in 1913 on tlie Canary Islands, and was 

 worked out tdgether with Prof. L. Miiller. A more detailed 

 account of the (^anarian Lizards, containing all described 

 species, accompanied by coloured plates, is in preparation. 

 For the present, it has seemed useful to give a preliminary 

 account of the more noteworthy points, together with dia- 

 gnoses of some new local races of Lacerta galloti, Diim. et 

 Bibr. We have to thank Ilofrat Dr. Steindachner, at 

 Vienna, for having sent us for comparison some lizards of 

 O. {Simony's collection, preserved in the Hofmuseum.
