Jordan and Evcrmaun. — Fishes of North America. 2835 



male the base of the anal is forward of that of the dorsal, the fin is modi- 

 fied to form a 8hari)-pointed organ in which the rays are less changed than 

 in most species; its length is less than that of the head. A''entrals small, 

 not reaching the anal. Pectorals reaching back over 7 scales. Caudal 

 deep, as long as the head, hind margin rounded. Scales large. Intestine 

 long. Brownish, olive tinted, bases of scales dark, back darker, and top 

 of head darkest; more or less of the hind margin, or \ of the scale, is 

 whitish to silvery on the scales of the flank; lighter to silvery under head 

 and abdomen ; dorsal with 1 to several transverse series of small spots 

 of black ; fin sometimes black tipped ; a brownish streak extending back 

 and upward on the opercle liehind the eye; caudal with small spots of 

 black on the basal half, or with a couple of clouded transverse bands; 

 other fins uniform or puncticulate; very small ones are lighter with a 

 laint silvery band along the middle of the flank, but without vertical 

 bars; a large one has numerous small white spots, somewhat like Fiindulus 

 heteroclitus. Females 2i and males Ii'-q- inches. Turbo, Gulf of Darien. 

 Pcecilia cuneata, Garman, Cyprinodonts, 62, pi. 5, fig. 3, 1895, Turbo, Gulf of Darien.

a Ho 8cl<>ral cartilages ; no pigment in or about the eye ; retinal elements readily sepa- 

 rable into ganglionic, inner reticular, and nuclear layers, the nuclear and outer 

 reticular layers rarely dlstiguishable; diameter of eye about .150 mm. 



SUBTERRANEUS, 1047. 



aa. Scleral cartilages large, forming a hood over front of eye; a mass of pigment in 



• front of eye; pigment layer of retina with more or less pigment; eye a mere 



vestige, about .040 mm. in diameter. KOS^, 1047(a).

Extremely close to T. suhterraneus, from which it seems to differ only 

 in the less developiuent of the eye. Scleral cartilages large, forming a 

 hood over the front of the eye; a mass of pigment in front of eye; pig- 

 ment layer of retina with more or less pigmi^nt; eye a mere vestige, i the 

 size of that of T. suhterraneus, about .040 mm. in diameter. The tyjies of 

 this species are 2 small, thoroughly dissected specimens, in the Museum 

 of Indiana University, collected from a cave in Jasper County, Missouri, 

 by Miss Ruth Iloppin. (Named for Mrs. Rosa Smith Eigenmann.)

Page 729 : 



Exocu'tus volitans, Linnnpus, as Loanberg has shown, is identical with E. 

 evoluns L. As the genus Exocatus, Syst. Nat., Ed x, 316, is based solely 

 on Ejocatus volitans, the name Exocatus must go with this species, taking 

 the place of Halocypselus. Tlie ordinary flying fishes must therefore be 

 called Cypsilurus. The species with long anal fin may, however, be held 

 as generically distinct from the type of Cypsilurus, and for them {exsilicns, 

 rondeletii, etc.) the name Exonautes has been proposed by Jordan & Ever- 

 maun, Chock List, 322. (Type, exsiliens.) (£%o, out of; vavn}i, swimmer.)
