LASIOPVGA 361 



The white on side of head and neck of the type is very extensive 

 and forms a broad collar nearly around the neck, only divided by the 

 narrow line on hind neck. The specimen appears to have no history 

 beyond the fact that it was given by M. Portier-Prohou, that it died 

 in the Menagerie on May 5th, 1887, and that it may have come from 

 West Africa.

While having a general resemblance to L. albitorquata Pou- 

 sargues, it will be seen, by comparing the above with the description of 

 the type of the allied species, that there are several important differ- 

 ences between them in coloration ; such as the color of the inner side
