Chiton {IschnocMton) sp. — Dr. Gwyn Jeffreys considered this to be 

 C. Rissoi, Payr. ; but out of 30 or 40 very small and separate valves which 

 I collected, about half are those of the head alone, not one is of the tail, 

 and on none is the girdle preserved ; so that the species cannot be deter- 

 mined with any confidence.
