40 FISHES FROM BRAZIL 



appears by the time they are 2 inches long. On both sexes the scales are 

 bordered with brown, and the upper and lower rays of the caudal some- 

 times bear a spot irregular in size, and varying in color from black to its 

 complete absence. 



Family BELONID^. 



121. Tylosunis almeida (Quoy and Gaimard). 



Specimens were secured at Lake Papary, Natal and Para. 



Family HEMIRAMPHID.^. 



122. Hyporh^mphus unifasciatus (Banzani). 



Numerous specimens from 6 to 10 inches in length were taken at Natal. 

 None of them has the mandible, from the tip of the upper jaw, shorter than 

 the rest of the head, as stated by Jordan and Evermann (Fishes of N. and 

 Mid. Am. p. 720), nor are the ventrals always inserted midway between the 

 eye and the base of the caudal, but their insertion varies from that point to 

 midway between the base of the caudal and the gill opening as in Hypo- 

 rhamphns rosce. These specimens were compared with some from Jamaica 

 and found to agree in all of their characters. 



Family EXOCCETID^. 



123. Cypselurus rubescens (Rafinesque). 



A large specimen of this fish flew on board of our steamer while en 

 route between Ceara and Natal. The light area on the pectoral is not nearly 

 as large or distinct as usual. 



Family SYNGNATHID^. 



124. Hippocampus punctulatus Guichenot. 



A few specimens of this form were collected in the harbor at Natal. 



Two distinct color phases are represented, but no other differences ap- 

 pear. The following colors were taken from live female examples. The 

 only male collected is of the color of the second one here described. 



( 1 ) The lower parts of the head, belly and tail are bright canary yel- 

 low, and the upper parts are yellowish green. Two dark brown cross bars 

 occur between the head and the dorsal fin. The second one is more con- 

 spicuous, covering two rings, and covered with irregular, longitudinal, white 

 lines. A third cross bar is on the tail four rings behind the dorsal. Be-
