Mr. Theobald has made species S. obscurus and S. crassus 

 of two solitary museum specimens, but they appear to be 

 aberrant varieties of S. bicatenatus. (J. A. S., 1868.) Indeed, 

 nearly all the species of this genus may be referred to two 

 t3'pes, S. bicatenatus and S. russellvi.

 depressed and elongate snout. Eye small, generally with
