Thomas, which seems referable to GoMesox macroplitlialmus, differing in 

 the slightly shorter dorsal and larger eye : 



"Dorsal 6 or 7; anal about 7; head about 3; width of body 3; width 

 of mouth 2 in head; interorbital width 44, equal to snout. Eye large, 2i 

 in head. Teeth in the upper jaw conic, in more than 1 series in front, 

 some in the outer row enlarged; teeth on the lower jaw in a single series, 

 about 4 blunt incisors on each side followed by the canines, behind which 

 the teeth are much smaller and conic. Width of disk If in its length, 2| 

 in head; opercular spine strong; distance of origin of dorsal from caudal 

 2| in its distance from tip of snout. Sides and back uniform bright red; 

 eye black, iris bright red; lower surface yellow, dotted with bright red. 

 One specimen 23 mm. long in the Museum of the University of Indiana 

 from St. Thomas (Coll. Edward W. Brigham), much shrunken and fins 

 hardened by strong alcohol." (Eigenmann, in lit.)

2673. GOBIESOX CERASINUS, Cope. 



Head 3 in total with caudal. D. 6 ; A. 6 ; C. 12 ; P. 24 ; V. 4. Head very 

 wide, ovate, as broad as long to upper base of pectoral. Eye large, 3 in 

 head, equal to frontal width. Ten teeth on each side of each jaw, none of 

 the upper being incisors, the 2 median on each side larger than the others ; 

 3 teeth on each side in lower jaw horizontal, the others vertical, 2 of 

 the horizontal teeth incisors, the median one on each side of these much 

 the larger ; each horizontal tooth with a small one behind it ; no canines. 

 Profile regularly descending from supraoccipital ; a long subopercular 

 spine. Dorsal beginning with last fourth of distance between tip of 

 snout and base of caudal. Body and fins light crimson lake above, whitish 

 below ; no spots. One specimen, 2 inches long, from St. Martins. (Cope.) 

 (Kspa<5iro$, cerasinus, cherry color.)

 Adolph Fred. (tab. 27), said to be 2 inches in length; the head broad with a sharp 

 spine behind; dorsal rays 6; not Lepadogaster nudus, BLOCH & SCHNEIDER, Syst. 

 Ichth., 2, 1801, who give "D.12, A. 6,"* the description otherwise that of Linnaeus: 

 not Gobiesox nudus of recent authors, which is a species (6. gyrinus) allied to O. vir- 

 gatulus.

 2674. GOBIESOX ERYTHROPS, Jordan <fe Gilbert. 



Head 2^; depth 6. D. 6; A. 5. Head scarcely longer than broad, pro- 

 portionately very broad and depressed, its breadth 3 times in total. 



* We do not know by what authority the number of fin rays given by Linnaeus (D. 6) 

 was altered to " D. 12, A. 6 " by Schneider (Syst. Ichth.). The last-named figures agree 

 with nudug, as described by Dr. Giinther, that is, with our G. gyrinus. If the Linnsean 

 type of nudus really had D. 6, it must have been cerasinus or macrophthalmus or some very 

 similar species. The scanty Linnsean description agrees best with cerasinus. The name 

 nudus, if used at all, must be taken for a species to which the Linngean description may be 

 applied. In our judgment the uncertainty is too great to justify the substitution of nudus 

 for either ceratinus or macrophthalmut. It could be no other known species, however. 



t This subgenus is composed of small species with the upper teeth in 1 series. This 

 character should be verified on all our species, as perhaps none of them belongs to it.
