a species very close to T. marinus, differing chiefly iii the smaller eye 

 (3 to 3^ in postorbital part of head) and in the fewer fin-rays (D. 13 or 

 14; A. 15 or IG). The type of Belone almeida Q. «& G. is regarded by 

 Valenciennes as identical with his B. timiicu, but the scanty description 

 of Quoy and Gaimard is of little value for purposes of identification. 

 The species was named ibr Don Fr. Almeida, a young secretary of the 

 Portuguese legation at Paris. 



This species may be the Timucu of Marcgrave, and therefore the 

 original Esox hrasiliensis of Linnieus, but the figure of Marcgrave looks 

 even more like the T. suhtruncatus than like T. almeida. 



Doubtless further material will show T. almeida to be the southern 

 representative or subspecies of T. marinus., as supposed by Dr. Giin- 

 ther, and the two may be wholly inseparable.

Habitat. — Pacific Coast of Mexico ; Mazatlan. 



This very large and robust species has been thus far found only 

 about Mazatlan. It represents on the Pacific coast the raphidoma of 

 the Atlantic.
