podial bones; two small metatarsal tubercles; the hind limb

 spots on dark ground color of upper surface of femur; a few 

 small white spots on the dark posterior face of femur; edge of

SYRRHOPHUS CYSTIGNATHOIDES (Cope) 



1877. Phyllobates cystignathoides Cope, Proc. Amer. Philos. Soc, vol. 17, no. 100, 

 p. 89, July 20. 



Type locality. — Potrero, near Cordoba, State of Vera Cruz, Mexico. 



Range. — Not known to occur elsewhere than at the type locality. 



Remarks. — Cope stated that "numerous specimens of this species 

 were found by Francis Sumichrast at Potrero, near Cordoba, Vera 

 Cruz, under the decayed trunks of trees." No other observations on 

 its habits have been published. There are now eight specimens in 

 the jar containing the cotypes of this species, although it is possible 

 that a larger series was loaned Cope. At that time Cope was actively 

 engaged in extending our knowledge of the herpetology of North and 

 South America, and incoming material apparently was often shipped 

 by the Smithsonian Institution directly to Cope without being un- 

 packed. Cope managed to publish reports on these collections about 

 as fast as they were received. The cotypes of cystignathoides have 

 the fronto-parietals meeting medially, eliminating the fontanelle. No 

 type is designated, and only one specimen (U.S.N.M. No. 32402) 

 has the skin dissected away from the cranium to expose the fronto- 

 parietal region. The following measurements were taken from a 

 cotype (U.S.N.M. No. 32404): Head-and-body length, 22.5 mm.; 

 transverse diameter of tympanum, 1.2 mm.; transverse diameter of 

 eye, 3 mm.; anterior edge of eye to nostril, 2.3 mm. It is quite pos- 

 sible that these cotypes may be the young of Leptodactylus melano- 

 notus, as all of them have a dark occipital spot that extends laterally 

 upon the upper eyelids in the posterior interorbital region. 



Specimens examined. — The eight cotypes (U.S.N.M. Nos. 32402- 

 09) collected by Francis Sumichrast at Potrero, near Cordoba, Vera 

 Cruz. 



SYRRHOPHUS GUTITLATUS (Cope) 



1879. Malachylod.es guttilatus Cope, Proc. Amer. Philos. Soc, vol. 18, no. 104, 

 p. 264, June 20. 



Type locality. — Guanajuato, State of Guanajuato, Mexico. 

 Range. — So far known to occur only in the sierras of southern San 

 Luis Potosi and in the vicinity of Guanajuato.
