EDWIN CHAPIN STARKS 



17. Pristigaster cayanus Cuvier. 



A couple of fine specimens were collected by Dr. Baker and Mr. Mann 

 in the Madeira River about 400 miles above its mouth. 



Family ENGRAULIDID^. 



18, Anchovia clupeoides (Swainson). 



Several specimens from 5 to 8 inches in length were taken in Lake 

 Papary. The anal rays vary fom 28 to 32 (not counting those in front of 

 the first long one), but are usually 30, as described by Dr. Steindachner. 

 His specimens were from 3^ to 5 inches ("9 to 12 cm.") in length. The 

 smallest specimens at hand agree very well with his description, but the 

 large ones are much deeper, the depth being much greater than the length 

 of the head, and is contained from 3 to sy^ times in the length of the body, 

 while the head is contained from 3^ to 4 times. 



19, Anchovia januaria (Steindachner). 



Specimens that answer very well to the description of this species, 

 which has hitherto been known only from the harbor of Rio Janeiro, were 

 taken in abundance in the harbor of Natal. 



20. Anchovia pallida Starks, new species, 

 Plate 1. 



The head and body are deep and compressed. The depth is equal to 

 the length of the head and is contained 3^^ times in the length of the body 

 to the caudal base. The snout is shorter than the eye and projects almost 

 its full length beyond the tip of the mandible. The maxillary is broad 

 and rounded behind, and scarcely reaches to the posterior end of the 

 mandible. Small even teeth are present in both jaws. The diameter of the 

 eye is contained 4j4 times in the head, and 2^ times in the postorbital part 

 of the head. The interorbital width slightly exceeds the length of the snout. 

 The cheek is long and triangular, and measuring from the eye to the lower 

 angle of the preopercular ridge, its length is twice that of the eye. The 

 greatest width of the opercle is no greater than that of the eye. Forty 

 slender gill-rakers, barely as long as the eye, are on the lower limb of the 

 first gill arch. 



The front of the anal is under the middle of the dorsal base, and the 

 front of the dorsal is midway between the base of the caudal and the front 

 margin of the eye. There are 14 dorsal rays, counting 2 rudimentary ones
