This species seems to be the original Scomber minutus as figured by 

 Bloch. Gazza equulcEJormis of Riippell seems to be the same, and there 

 is nothing in the description of Gazza argentaria (Forster) or Gazza 

 dentex Cuvier & Valenciennes to indicate specific difference. The 

 measurements of Gazza equulceformis fit our specimens best. 



63. Gazza achlamys^ Jordan & Starks, sp. nov. (Plate XLV.) 



No. 80740, C. M. Type; Nos. 80750-6, C. M., Paratypes. 



Head two and four-fifths times to two and seven-eighths times in 

 body without caudal; depth one and four-fifths times in length; dorsal 

 VIII, 16; anal III, 13 or 14; gill-rakers fourteen on lower limb of arch. 



Anterior profile of top of head and mandible slightly concave. 

 Eye slightly larger than in Gazza minuta, two to two and one-half times 

 in head. Maxillary reaching to under front of pupil, its Exposed part 

 equal in length to two-thirds the diameter of the eye. Ascending 

 limb of premaxillary scarcely reaching to above the posterior margin 

 of the eye. Width of maxillary as in G. minuta. Depth of cheek 

 below eye a little greater than in G. minuta, equal to length of snout 

 from front of pupil. 



Spines and serrations of supra-orbital ridge about as in G. minuta, 

 but the serrations on lower limb of pre-opercle very much coarser. 

 Teeth similar to those of G. minuta, but only about one-third as large, 

 and there is less discrepancy in size between the anterior mandibular 

 teeth and those behind them. Two small processes on shoulder- 

 girdle as in G. minuta. 



Dorsal spines rather stiff, much stouter than in G. minuta, the second 

 equal in length to the head behind the middle of the eye, and a little 

 shorter than the length of the pectoral. Anal spines of about the 

 same length, but very thick as in G. minuta. Ventral fins reach three- 

 fourths to four-fifths the distance from their base to front of anal. 



Body naked anteriorly to a line running from the front of the soft 

 dorsal obliquely downward to behind the pectoral base and thence 

 downward and backward to the front of the anal. The scales have 

 not been lost, as with a lens one may appreciate that they are smaller 

 and unimbricated where they begin gradually to develop. The lateral 

 line runs to the base of the caudal. 



Color dusky above, silvery on sides and lower parts, no wavy lines 

 on back, except in specimens from the Philippine Islands, where indis- 



1 dxXapuj = without a cloak, referring to the scaleless back.
