i 94 i CATALOGUE OF FISHES OF TORTUGAS 33 



First D. 14, 2 specimens counted (Goode and Bean gave only 11) ; P. 17; V. 8. 

 Gill rakers very short and thick, and beset with spinules, 7 on lower limb of first 

 arch. Head in total length 6.0; depth 7.2 to 7.8; distance from snout to origin of 

 first dorsal 5.1 to 5.3. Eye in head 3.3 to 3.5; snout 3.7 to 4.1; interorbital 4.1 to 

 4.5; pectoral 1.8. 



General color brownish; abdomen and branchiostegal membranes dusky to 

 black; distal part of first dorsal and axil of pectoral dusky. 



In deep water off the south Atlantic states and in the Caribbean Sea. 



S. F. H. 



Macrourus holotrachys Giinther 



Five specimens, ranging in length from 170 to 190 mm., are in the Tortugas 

 collection. Though without definite data, the specimens quite certainly were 

 taken in the deep channel south of Tortugas at a depth somewhere between 140 

 and 393 fathoms. 



This material seems to fit Gunther's description and figures (Ann. and Mag. 

 Nat. Hist., ser. 5, vol. 2, 1878, p. 24) fairly well, though the species apparently 

 has not been recorded off the North American coast. This species is characterized 

 chiefly by the high number of ventral rays (9), and by 3 spiny prominences on 

 the margin of the snout, a large central one and a smaller one on each side. The 

 vent is near the base of the ventrals, being much nearer to these fins than to the 

 origin of the anal. 



A few discrepancies between Gunther's description and the specimens at hand 

 are evident. Giinther stated that the snout was as long as the eye, whereas in the 

 Tortugas material it is shorter than the eye. He also stated that the origin of the 

 second dorsal was behind the first dorsal scarcely the length of the base of the 

 first. I am unable to find any rays or stumps of rays nearer than about twice the 

 length of the base of the first dorsal in the somewhat damaged specimens at 

 hand. 



The following proportions and enumerations are based on the 4 specimens in 

 the collection: Head in total length 5.75 to 6.25; depth 7.0 to 8.0. Eye in head 2.5 

 to 3.1; snout 3.4 to 3.7, its projection beyond tip of lower jaw 3.5 to 3.8; inter- 

 orbital 4.6 to 5.2. D. about 124 to 150; A. about 100; P. 19 to 21 ; V. 9. 



Color mostly brownish; abdomen, opercle, and lower parts of head dusky; 

 orbit margined with a black line; anterior rays of first dorsal distally black. 



Deep water off the mouth of the Rio Plata, now for the first time from Florida. 



S.F.H. 



Coelorhynchus carminatus (Goode) 



This species is listed as the "rough rattail" by Dr. Longley. It apparently is as 

 common as Chalinura occidentalis, with which it often was taken. Many speci- 

 mens were caught in 180 to 393 fathoms. 



It is recognized by the extremely rough scales, the free parts of which are 

 covered with sharp spines; margin of snout and ridges of the head also rough, 

 with spinules; snout depressed, projecting nearly its full length beyond mouth, 

 flat or even slightly concave underneath; 2d dorsal spine perfectly smooth; 2d ray
