OBSERV. Whether the species which we describe below is truly 

 congeneric with Lipinia pulcJiella, GRAY, we are not prepared to decide 

 for the present, since no description of the latter has as yet been fur- 

 nished. 



The present genus, as here characterized, differs from OUgosoma, to 

 which it bears strong affinities, in the dorsal scales not being larger on 

 the two middle series, the weaker and more distant limbs, the exigu- 

 ous fingers and toes, arid the coarsely granular or rather tubercular 

 structure of the palms and soles. 



Moreover, its scales are perfectly smooth, a character which will 

 distinguish Lipinia from both, OUgosoma and Lygosomella. In the 

 latter, the limbs are much wider apart, and the fingers and toes more 

 developed than in Lipinia. The tubercles over the palms and soles 

 are also less developed in Lygosomella than in the genus here referred 

 to.
