98 BARBOUR — SOLOMON ISLAND REPTILES [^vll^v^lF 



Islands. It evidently is common. Dr. Mann collected the fol- 

 lowing specimens: fifty-seven from Bio Island, a small islet 

 near Ugi; three from Ysabel; one from Santa Ana; two from 

 San Cristobal; one from Graciosa Bay, in the Santa Cruz 

 Archipelago, east of the Solomon Islands and northeast of the 

 New Hebrides. 



Rana guppyi Boulenger 



Rana guppyi Boulenger, P. Z. S., 1884, p. 211. Rec. Indian Mus., 20, 

 1920, p. 113. 



A really enormous species, by far the largest member of the 

 subgenus Discodeles. It has been found on many of the Solo- 

 mons, but not outside of the Group. Boulenger records the 

 species from New Georgia and Rubiana Islands, among others, 

 but Dr. Mann informs me that the name Rubiana applies to a 

 lagoon on New Georgia, as the literature also indicates. He 

 caught four of these great frogs upon Malaita, apparently a 

 new locality. The specimens previously in the Museum were 

 from Guadalcanar. 



Rana bufoniformis Boulenger

 Rana opisthodon Boulenger, P. Z. S., 1884, p. 211; Rec. Indian Mus., 



20, 1920, p. 111. 



Apparently the only specimens of these frogs which Boulenger 

 had seen when he wrote his revision of the Australasian species 

 of Rana, were the type and one other female of bufoniformis and 

 five specimens of what he called opisthodon. The characters 

 supposed to separate the two species follow : 



Tympanum about one third diameter of eye; tibio-tarsal 

 articulation reaching temple; tibia two and one fourth to two
