Biifo marinns (Linnaeus). — This toad was very common in 

 the region about Dunoon. It was found in nimibers in the low 

 forest along the river, less abundantly in the forest on the sand 

 reef, and occasionally in the thickets on the mouries. Tad-

 some of them left the water on August 16 (Copeia, No. 31, 

 pp. 43-44). The following description of the tadpole has been
