Ohs. — This peculiar species appears to approach the 

 genus Ophites in some of its pecidiarities ; it is the most 

 remarkable Cri/ptobium known to me, and I have very 

 great pleasure in naming it in honour of its discovei'er. 

 Dr. Trail, to whom I am indebted for the only individual 

 known of it.

* I had written this word S2)ha;rinnm,a.x\A it so stands in the list of species 

 at the commencement of this paper ; but as Erichson has used the word 

 Spharina for a genus of Coleoptera, I have thought an alteration necessary.
