GILBERT AND STAIJKS — FISHES OP PANAMA BAY 55 



Family EXOCCETID.E. 



104. Fodiator acutus {Cuvler tL- Vuleiicicnnef<). 



Abiimlfuit in Paiianiii Bay; many were seen flying, and four specimens were 

 taken, 14") to loS mm. in length. Tlicy agree well with the description of the type. 



105. Cypselurus callopterus {Gihither). 



Two specimens were collected, 25 and 31 cm. in length. They agree well 

 with Dr. Giinther's description and plate. 



106. Exonautes rufipinnis (Cuvier cC- Valenciennes). 



Only the type of Exocatus doivi Gill, 1863, p. 1G7, ( = E. rufiinnnls), is 

 known from the vicinity of Panama. 



Family FISTULARIID^. 

 107. Fistularia depressa Giinther. 



A single large specimen was taken in the market at Panama. 



We have examined specimens from Japan, Plonolulu, the Philippines, and 

 La Paz, L. C, and can distingnish no diflferences between them. In the figure of 

 this species given by Dr. Giinther (Shore-fishes, Challenger, Plate XXXII), the 

 greatest width between the diverging ridges on the anterior part of the snout is 

 indicated at a point too far forward. In our specimens the ridges are farthest apart 

 at the beginning of the anterior f or | of the snout. The interorbital area appears to 

 be more concave in small specimens (25 cm. in length) than in the larger ones. In 

 the latter the interorbital is contained 51 in the postorbital part of the head. In 

 specimens 50 cm. in length the orbit (measuring the extreme length between the 

 bones surrounding the eye) is from 9[ to 9f in the head, and the length of the max- 

 illary is 9i. In a specimen 69 cm. in length, the maxillary is contained 10 times 

 and the eye 11 times in the head. 



A large number of small s^Jecimens 25 to 28 cm., and one sjjecimen 41 cm. in 

 length from Honolulu, are plain brown on the back, while a larger specimen 61 cm. 

 long has blue spots, as in our Panama specimen. Four specimens from La Paz, 

 51 cm. long, all show blue spots. The following color description was taken from 

 our Panama specimen in the fresh condition. 



Olive-brown on upper parts, white below. A pair of narrow blue stripes, 

 inteiTupted anteriorly and posteriorly, begin at the nape, diverge backward and cross 

 the lateral line just in front of the point where it becomes straight, then run just 

 above and jjarallel to the lateral line as far as the tail. Another pair of streaks, made 

 each by a series of blue spots, runs close along each side of mid-dorsal line, from a
