2 6 PAPERS FROM TORTUGAS LABORATORY vol. xxxiv 



Longley collection. Three, 47, 49, and 130 mm. long, were measured and their 

 fin rays counted, giving the results that follow: Head (to margin of opercle) 3.4 

 to 3.5; depth 6.5 to 7.0. Eye in head 2.7 to 3.0; snout 3.7 to 4.3; interorbital 11 to 

 14; maxillary 2.2 to 2.4; caudal peduncle 4.1 to 4.8; longest rays of pectoral 1.3 

 to 1.4. D. 11; A. 8; P. 15 or 16; V. 8 or 9; scales in lateral line about 52. The 

 smaller specimens are barred and blotched above with dark gray, whereas the 

 largest specimen is almost plain. The vent in each specimen is conspicuously sur- 

 rounded with black. 



These specimens differ somewhat from the type in the position of the ventral 

 fins, which are inserted well in advance of the middle of the base of the dorsal 

 instead of under the middle, and in that of the adipose, which is situated over the 

 anterior half of the anal instead of over the middle of it. Small differences also 

 are evident in the proportions and counts given. All these differences, however, 

 may constitute variations within the species. I follow Regan (Ann. and Mag. 

 Nat. Hist., ser. 8, vol. 7, 1911, p. 126) in placing this genus and species in the 

 family Sudidae.

Chlorophthalmus truculentus Goode and Bean 



Eighteen specimens, 180 to 237 mm. long, were taken July 31, 1930, in one haul 

 in 180 to 220 fathoms. Both males and females were in breeding condition. The 

 fish were dusky dorsally and pale ventrally, having no pattern; caudal dusky; 

 dorsal dusky at tip. In another haul 9 were taken in 220 to 237 fathoms. Eight 

 specimens, 180 to 200 mm. long, were taken in still another haul in 205 to 221 

 fathoms. 



This species is distinguished from the preceding one by the more produced, 

 sharper snout; smaller mouth, with maxillary failing to reach front of eye; 

 scales cycloid instead of pectinate; shorter dorsal with only 9 rays; and plainer 

 color. 



Four specimens are deposited in the U. S. National Museum, ranging in 

 length from 152 to 163 mm. In 3 of these the dorsal consists of 10 rays, and in 1 

 of 9; in 3 the anal has 9 rays, and in 1 it has 10.

Neoscopelus macrolepidotus Johnson 



A specimen of this deep-sea fish was taken at a depth of 367 to 375 fathoms. 

 Concerning the color of this specimen Dr. Longley wrote: "In posterior angle 

 of each luminous organ a red spot. Bases of pectoral reddish. Red chromato- 

 phores sparsely scattered on all the fins, and on head." 



Five specimens of this species, respectively 73, 80, 80, 98, and 135 mm. long to 

 base of caudal, are included in the Tortugas collection, all without specific data. 

 The specimens all have broken and frayed fins. The following enumerations and 

 proportions are based on the two best specimens: Head 2.8 to 3.05; depth 4.1 to
