Remarks. — Brought by Dr Gibbon from his recent expedition to 

 South America. It very closely resembles C striata (nobis), but may 

 at once be distinguished by its longitudinal striae, the striata being 

 transversely striate. The specimens were generally worn. That which 

 is represented is the only one which had any part of the epidermis 

 remain ng.
