Genus PHYLLODACTYLUS Gray 



PHYLLODACTYLUS ABRUPTESERIATUS Werner 



1912. Fhyllodactylus abnipteseriatus Werner, Jahrb. Hamburg Wiss. Anst., 

 Beiheft 2: Mitt. Naturh. Mus. Hamburg, vol. 30, p. 4 (type locality. 

 " wahrscbeinlich Brasilien"). 



This species was described from a specimen which was thought to 

 have come from Brazil, but two examples from Ecuador in the col- 

 lection of the United States National Museum, No. 14053, secured ' 

 on December 18, 1884, by Dr. William H. Jones, show the twelve 

 longitudinal rows of enlarged dorsal tubercules, the third and sixth 

 (outer) on each side much shortened, attributed to this form. P. 

 ahrupteseriatus, like P. ffuayaquilensis, is very closely related to P. 

 tuberculosus. All three of these described forms apparently occur 

 in the same general range in Ecuador and possess the same general 

 colorational and scutellational features, except in regard to the ar- 

 rangement of the dorsal tubercules. Morphologically, ahrupteseri- 

 atus and guayaquilensis are more closely related than either of these 

 ! and tuherculosus., for the former lizards possess twelve longitudinal 

 I rows of enlarged dorsal tubercules, some of which are shortened, 

 whereas the latter possesses fourteen rows, more of which are full- 

 sized. 



PHYLLODACTYLUS BAESSLERI Werner 



1900. Phyllodactylus baessleri Werner, Abhandl. Ber. Zool. Anthropol.-Ethn. 

 Mus. Dresden, vol. 9, no. 2, p. 2 (type locality, Chanchamayo, Peru). 



One of these lizards. No. 38569, collected at Las Vocas landing, 

 near Capon, region of Tumbe, Peru, by R. E. Coker, has 12 longi- 

 tudinal rows of enlarged dorsal tubercules, the lower on each side 

 being much shortened, however. In coloration and general appear- 

 ance the species closely resembles P. tuberculosus and P. magister.
