Lcptodactylus caliginosus Girard. — A large series of speci- 

 mens. The species was very common at Dunoon and was found 

 only in the low forest, swamps, ditches, and clearings along the 

 river and creeks. During the day it was found under logs, but 

 at night it was active and could be collected in numbers with a 

 light. The coloration is variable but a common type may be de- 

 scribed as follows : Ground color above grayish olive with 

 darker markings, the only constant ones being the blackish 

 band from the end of snout to axilla and a large triangular 

 olive brown, black-edged spot on the head; belly white with 

 olive brown reticulations; posterior sides of thighs with an 

 irregular pattern of black and old gold. In some of the 

 specimens the darker markings are faint or wanting, the 

 ground color above being russet with kaiser brown punctula- 

 tions. 



Lcptodactylus rliodouiystax Boulenger. — Two specimens 

 obtained in the forest on the lower part of the sand reef cor- 

 respond very closely to the original descrijjtion of the species. 

 The margin of the upper lip was terra cotta in life, the broad 

 stripe under the eye and the spots at the angle of the mouth, 

 white. The length of the two specimens is 18 mm. and 20 mm. 



Lithodytes lincatus (Schneider). — A single specimen taken 

 in a pile of chips in the forest on the sand reef at Dunoon. 



Noble* has concluded that this species is to be referred to the 

 genus Lcptodactylus for the reason that with age there is a 

 change in the form of the distal digital phalange from an 

 "Eleutherodactylus-like T-shaped type" to a ''Leptodactylus- 

 like simple type," and a similar change occurs in the ontogeny 

 of a typical species of Lcptodactylus. L. niclanonotus. In the 

 opinion of the writer Noble's argument fails to be convincing
