of caudal peduncle become more strongly keeled and dentate. Spinous 

 dorsal and anal depressible in grooves. 



Spinous dorsal inserted nearly midway between front margin of orbit 

 and origin of soft anal in vertical. Third erect spine longest, others 

 graduated down. Soft dorsal inserted about midway in length of 

 trunk, and first rays longest. Spinous anal inserted a trifle before 

 origin of soft dorsal, spines nearly equal. Soft anal similar to soft 

 dorsal, only inserted more posteriorly. Caudal rather small, forked, 

 and lobes apparently pointed. Pectoral rather long. Ventral in- 

 serted well behind pectoral and reaching a trifle over § of space to origin 

 of spinous anal. 



Color in alcohol faded pale dull slaty-gray above, below pale brown- 

 ish-white. Fins dull brown. Iris pale yellowish. 



Length (end of caudal damaged) 7h inches.

It also agrees with twenty-one examples from Italy, of all ages. 

 Bonaparte Coll. (No. 377). Dr. T. B. Wilson. One also from Malaga. 



Dr. Steindachner first pointed out this form, basing it on Mediterra- 

 nean examples with an increased number of scutes in the lateral line, 

 79-86. T. trachurus is said to have 70-75.

St. Thomas (West Indies), San Domingo (West Indies), New Provi- 

 dence (Bahamas), Santa Cruz (West Indies), and Newport (Rhode 

 Island). Examples from the Pacific do not appear different. An 

 example from Panama (Coll. J. A. McNeil) has: Head 3; depth 3f ; D. 

 I, VIII-I, 26; A. II-I, 23; scales in lateral line 48, and remaining 

 keeled scutes 33 (81) ; pectoral 1| in head; snout 3f in head, measured 

 from tip of upper jaw; eye 3; maxillary 2^; length 9| inches. An- 

 other example from Samoa differs in: Head 3j; depth 3|; A. II-I, 

 22; 54 scales in lateral Hne, and remaining keeled scutes 35 (89); eye 

 Sh in head, measured from tip of upper jaw; snout 3^; maxillary 2f ; 

 length 7| inches. Smaller Hawaiian examples*" differ in minor details. 



I provisionally follow Dr. Giinther in identifying all these examples 

 with Bloch's crumenophthalmus, though possibly exhaustive material 

 may prove different.
