On the 12th June, 1920, Mr. C. W. Sherwood, of New Brighton, 

 presented to the Canterbury Museum a small shark which he had found 

 on the New Brighton beach. It is considered to be a new species of 

 Scymnodon, a genus of small sharks living in deep water, and is named 

 after its discoverer.

 between them three-fifths of preoral length of snout. Length of anterior 

 labial fold about equal to its distance from the symphysis.
