Only two specimens of this shark have been recorded — the 

 type described by O'apello from the coast of Portugal, and an 

 example about 9 feet, 8 inches long which came ashore in ex- 

 cellent condition at the Amagansett life-saving station on Long 

 Island, Feb. 8, 1883. The latter specimen was forwarded to the 

 U. S. National Museum, Washington D. C. 



A figure of the species is published in Oceanic Iclithyology, pi. 5^ 

 fig. 17.
