The very youug specimens on vdiicli this species was based, evidently 

 belong to the species which we have lately described as Lutjamis prieto, 

 an identification which could not be made from the description published. 

 The dark bands are a character of extreme youth. 



Serranus calopteryx Jor. & Gilb. (Proc. U. S. Xat. Mus. iv, 1881, 350) 

 seems to be identical with Prionodes fasciatus Jenyns (Voyage of the 

 Beagle, Fishes, 1842, 46). The absence of the vomerine and palatine 

 teeth in Jenyns' type is, as has been suggested by Dr. Giinther, purely 

 accidental, and without significance. The name fasciatus is preoccu- 

 l)ied in the genus Serranus, by Rolocentrus fasciatus Bloch. This spe- 

 cies may therefore retain the name Serranus calopteryx. 



34. Diabasis sexfasciatus (Gill) J. & G. 



{Hamulon sexfasciaius Gill, Proc. Ac. N;it. Sci. Phila. 1862, 2bA^HwmuJo)i maculostim 

 Peters, Berliner Moaatsber. 1869, 705.) 



3000. (Types of Hamulon sexfasciatus.) One specimen, 4 inches long. 



64C7. About twelve specimens of similar small size. 



This species reaches a very large size, and the adult examples are quite 

 different in form and coloration from the little fish which served as the 

 original type. As in related species, the black spots on the scales are 

 developed with age. 



35. Diabasis scudderi (Gill) J. & G 



{Ewmulon scudderii Gill, Proc. Ac. Nat. Sci. Phila. 1862, 253 = ^rt>nH/?on brevirosfrnm

 Beitriige, iii, 11, 1875:) 



3683. (Types of Ilccmulon scuddcril.) Three young specimens, in good 

 condition. The coloration is quite different from that of the adult or 

 half-grown of this species, and is extremely similar to that of the young 

 of Pomadasys hilineatus. 



Grayish, the scales with inconspicuous darker spots. A broad black 

 band through snout and eye, ending in a black blotch at base of caudal. 

 A second band from between nostrils on each side, above eye straight 

 to soft dorsal and upper edge of caudal peduncle. Fins, especially 

 anal, a little dusky. A dark blotch hidden by angle of opercle. All 

 these specimens have 12 dorsal spines, but most of those obtained by 

 Mr. Gilbert have 11, as in the type of Hwmulon undecimale. 



36. Diabasis sieindachneri Jordan & Gilbert. 



19879. Eight specimens, nearly adult, in good condition. These 

 appear to have been received alter the publication of Piofessor Gill's 

 l)apers. 



37. Diabasis flavignttatus (Gill) Jor. & Gilb. 



{Ha-mnlon Jlarifiutlatus Gill, Proc. Ac. Nat. Sci. Phila. 1862, 254 = Eamiilon margariti-

3681. (Type of Hwimilon Jfaviguttatus.) An adult example, in good 

 condition.
