GECKONID^E. 



6. Hemidactylus mabouia Mor. 



Common at Santos, and also in the interior, as for instance at 

 Santa Rita and Piracicaba. It is found in houses and also in the 

 forests. It does not seem that this distribution has been effected by 

 man's agency. In the large city of Sao Paulo I have never seen 

 this Gecko. 



IGUANIDJE. 



7. Tropidurus hispidus Spix.s 

 Common at Sorocaba. 



8. Enyalius catenatus Wied. 



There are two forms in Sao Paulo. One of them may be the true 

 catenatus or a closely allied species, having the disposition of the 

 spots and yellow marks somewhat irregular, not existing in all 

 forms as seen in the figures of Spix (Plates XI and XIII). The 

 second form, which I call variety paulista, has more affinity with E. 

 iheringi, but the position of the nostril is nearer to the end of the 

 snout than to the orbit, quite as in catenatus, to which the tibia shows 

 analogy. A dark spot passes from the superciliary region to the 

 upper lip. A series of alternating black spots is contained in the 

 obscure vertebral band. Two large yellow lateral bands exist as 

 well as in E. iheringi. This may be, therefore, a local variety of 

 iheringi, but differs in some characters. Moreover, the dark spots of 

 the face and of the extremities, especially of the lower legs, seem to 

 be characteristic of paulista, and wanting in iheringi. As I had 

 already doubts of the specific validity of iheringi, and as the new 

 variety is intermediate between iheringi and catenatus, I believe 

 that both are mere varieties of the latter. 



The description above given refers to the female, the male being 

 green without marks or spots, and not purplish as Boulenger says. 



Enyalius is not at all common and it will, therefore, be impossible 

 to obtain a sufficient representation for more conclusive studies 

 for some time. 



9. Anisolepis grilli Blgr. 

 Sao Paulo, St. Rita. 



10. Urostrophus vautieri I>. <V 1!. 

 Sao Paulo, St. Rita. 



3 1 have TV. torquatus Wied. from IJio de Janeiro, but that species seems to 

 be wanting in Sao Paulo.
