 upper ray longer than middle one, ventrals very long. Body slaty 

 brown, mottled with gray but without bands; dorsal with a bluish gray 

 band at base, then a bronze one, forking on soft dorsal, inclosing a bluish 

 gray band; 5 gray bands and 4 bronze ones on dorsal more or less distinct, 

 especially in young; anal with 5 bluish gray and 5 bronze bands more

 inches. Rocky shores on the west coast of Mexico from Mazatlau to 

 Panama; common at Mazatlan. Also obtained by Dr. Gilbert in 1881 

 at Mazatlan and Panama. These specimens having been destroyed by 

 fire, have never been described, and were provisionally and incorrectly 

 referred to the West Indian species Teuthis tractus (bahianus), from which 

 this species diifers in a few respects. (Named for Creston * Island, a com- 

 manding peak in the harbor of Mazatlan at the base of which this species 

 abounds.)

* " Beyond the headland with its palm tree lone 

 Flashes the heacon light on tall Creston ; 

 The last and haughtiest of the craggy horde, 

 Sierra Madre sends forth ocean ward.'"
