194 1 CATALOGUE OF FISHES OF TORTUGAS 89 



Because of the close relation between this species and A. planijrons, re- 

 cently described as new, it seems desirable to furnish additional data. The fol- 

 lowing proportions, enumerations, and remarks are based on 3 specimens from 

 Tortugas, ranging in length from 32 to 43 mm., and 1 larger one, 95 mm. long, 

 from Cuba (U. S. Nat. Mus. no. 37529): Head 2.5 to 2.75; depth 2.8 to 3.2. 

 Caudal peduncle in head 2.3 to 2.5; eye 2.9 to 3.5; snout 4.0 to 4.8; interorbital 

 4.5 to 5.3; maxillary 1.8 to 1.9; pectoral 1.7 to 1.9. D. VI-1,9; A. 11,8 or 9; scales 

 before dorsal 5 or 6, in lateral line 25, on caudal peduncle 2 or 3 above and below 

 lateral line in addition to a median dorsal and ventral series; gill rakers 12 or 13, 

 including rudiments, on lower limb of first arch; pectoral with 10 rays; pre- 

 opercular margin moderately serrate; 2d dorsal spine much stronger than 3d; 

 ventrals reaching vent; pectorals reaching origin of anal; body rather deep; head 

 not notably flattened above, the anterior dorsal profile being rather evenly 

 rounded.

Apogonichthys alutus (Jordan and Gilbert) 



No specimens were found in the collection, and nothing in Dr. Longley 's field 

 notes is identifiable with this species. However, in his copy of Jordan, Evermann, 

 and Clark's Cheeky list, this species is definitely checked and numbered, as his 

 custom was with species belonging to the Tortugas fauna. 



In his unfinished manuscript is the following: 



"Jordan and Thompson's suggestion [Bull. U. S. Bur. Fish., vol. 24, 1904 

 (1905), p. 239] that A. alutus is identical with A. puncticulatus [= A. stellatus] 

 I believe incorrect. The possibility of the two being growth stages of one species 

 is eliminated because the many small specimens of A. puncticulatus examined, 

 like the large ones, have long ventral fins. Sexual dimorphism also fails to explain 

 the difference, for specimens with well developed ovaries and others with as 

 evident spermaries are like one another in the same way. Besides the type (U. S. 

 Nat. Mus. no. 30874), and a specimen from Puerto Rico, the U. S. National 

 Museum has a Cuban specimen, 51 mm. (no. 37477), presented by Professor 

 Poey." 



Although Dr. Longley fails to state that this species was taken at Tortugas, it 

 surely may be expected in that vicinity, especially as there is at hand, in addition 

 to the specimens already mentioned, another one, 44 mm. long, taken oflf Beau- 

 fort (North Carolina) Inlet, in 13 to 14 fathoms. The Beaufort specimen agrees 

 closely with the type. The following proportions and enumerations are based on 

 the type and the Beaufort specimen, the ones based on the latter being enclosed 

 in parentheses: Head 2.6 (2.6) ; depth 2.9 (2.6, a gravid female). Caudal peduncle 

 in head 2.5 (2.6); eye 2.7 (2.9); snout 5.0 (5.2); maxillary 1.7 (1.6); interorbital
