BATRACHIAANOURA. 25 



The ground color is olivaceous ; the body and limbs above, macu- 

 lated with large brownish-black blotches, the latter much larger on 

 the hind legs ; the whole surface, from the snout to the tips of the 

 fingers and toes, is minutely dotted. The glandulous dorsal ridges 

 appear almost black by the accumulation of small spots and dots. 

 Faint traces of a narrow stripe exist between the eyes and the nostrils. 

 The belly is unicolor ; the margin of the lower jaw and the hind legs 

 being inconspicuously maculated. 



Log. — This species is a native of California.

4. Rana maritima, Risso. 



(Plate II, figs. 7-12.) 



Spec. Chae. — Diameter of tympanum nearly equal to the width of 

 the upper lid. Interocular space narrow. Interdigital membrane 

 deeply emarginated. Two glandular dorsal ridges; one on each side. 

 Body above covered with small pustules, largest upon the middle 

 of the back. 



Syn — Rana maritima^ Risso, Hist. nat. Europ. merid. III. 1826, 92. 



Observ. — In recording this species as distinct from Rana viridis, 

 with which it has been identified by Dum6ril and Bibron, and from 

 Rana temporaria, which it was labelled by the scientific corps of the 

 United States Exploring Expedition, we consider it our duty to state 

 that we are not yet fully satisfied of its real identity with Risso's 

 species. As it is, however, the one to which it comes nearest, we 

 have not deemed it expedient to multiply the names, already so 

 numerous, which have been bestowed upon European frogs. Risso
