5. CESTREUS PRZIDATORIUS. 
(Boccont.) 
Cestreus predatorius Jordan & Gilbert, sp. nov. (Panama). 
Habitat.—Pacific coast of tropical America, Panama. 
This strongly marked species was obtained by Dr. Gilbert at Panama 
in 1883, and by us described in MS. at the time. Our specimens were 
destroyed by fire, and the species has remained unnoticed. The types 
of the present description are three specimens, the largest nearly 2 feet 
in length, obtained by Professor Agassiz at Panama. These are num- 
bered 10901 and 10902 on the register of the Museum of Comparative 
Zoology. ‘The species is known to the Panama fishermen as ‘ Boccone.”
