Tlie specimens from Ashland agree with those from the Mc- 

 Cloud, except tliat thev are nearly black above and do not exhibit 

 the dorsal spots. 



I compare this species with the Bana temporai'ia aurora from 

 the Russian River near the coast of California. That species has 

 but one palmar tubercle, the internal, which is of similar propor- 

 tions to that of the R. pachy derma. The skin is not thickened, 

 and is much less glandular everywhere. The membranum tympani 

 is entirely distinct. The posterior face of the femur is not ver- 

 miculated with yellow, but is covered with large black masses. 

 The whole of the under surfaces are brown-spotted. There are 

 four brown crossbars on the tibia : traces of the fourth sometimes 

 appear in the R. pachyde7"nia. From Rana pretiosa it differs in 

 all these characters; besides those that belong to the latter, t. e., 

 the posteriorly-placed vomerine teeth and the short hind-legs.

The movements of this species are not nearly so active as are 

 those of the Iguanidse and especially of the Lacertidse. 



Scdoporus undulatus thayeri B. and G. 

 DiadopMs puuctatus pulohellus B. and G. 



Diff'erent from the tj-pical form of the subspecies in having no 

 spots on the inferior surfaces.' I did not admit this form as dis- 

 tinct in my check list, but it had best be retained. It differs 

 from the subspecies amabilis in having the inferior two rows of 

 scales unicolor with the abdomen. In life this is a brilliant 

 orange.^ 



• At this locality I found, under bark of logs, numerous specimens of 

 Brachycybe lecontei Wood. This beautiful myilapod was originally described
