they are here contrasted are characteristically slight, scarcely enlarged basally 

 before relatively advanced growth stages. 



"Scales in lateral line to base of the caudal 54 or 55; pectoral rays almost in- 

 variably 14; width between tips of preorbital processes of frontal bone moderate, 

 much less than in C. calamus of the same length, the processes themselves rather 

 sharp distally, not vertically expanded and blunt as in that species; cheek streaked 

 with horizontal lines, enclosing no rounded spots of the light ground color; the 

 lines often wanting in preserved specimens." 



In the Musee d'Histoire Naturelle, Paris, Dr. Longley examined the type speci- 

 mens (no. 5564) of Pagellus penna Cuvier and Valenciennes (Hist. nat. poiss., 

 vol. 6, 1830, p. 209 — Brazil). Concerning these Dr. Longley noted: "They are the 

 types of Pagellus penna and include two species. Two are those upon which the 

 description of P. penna is largely or exclusively based. The third specimen be- 

 longs to a species for which the earliest name available appears to be Pargus 

 quadrituberculatus." 



The proportions and enumerations given, copied from Dr. Longley's notes, are 

 based on the 2 type specimens of C. penna, having a total length of 137 and 147 

 mm. and a standard length of 106 and 116 mm.: Head 3.2, 3.4; depth 2.35, 2.4; 

 snout to preopercular border 4.3, 4.5. Eye in head 3.3, 3.1; interorbital 3.9, 3.6; 

 preopercular width 3.9, 3.6. Scales about 47, about 46; pectoral rays 15, 15. 



From the synonymy of C. penna, as given in some current works, Dr. Longley 

 extracted Pagellus microps Guichenot (in Ramon de la Sagra, Hist. lie Cuba, 

 1853, p. 188, pi. 3, fig. 1 — Havana). To the synonymy of C. microps he assigned 

 Gramrnateus medius Poey (Ann. Lye. Nat. Hist. New York, vol. 10, 1872, p. 183, 

 pi. 7, fig. 4 — Havana), and C. arctijrons Goode and Bean (Proc. U. S. Nat. Mus., 

 vol. 5, 1882 (1883), p. 425 — Pensacola, Florida). 



That Dr. Longley's findings, as set forth, were intended to be final I cannot 

 be positive. They seem well worthy of consideration, however, when further 

 studies are made. S. F. H.

The young of 55 mm. and over may be seined in Thalassia in shallow water, 

 and larger young of 70 to 160 mm. occur in the n-fathom channels. The adults 

 are generally distributed over the open reef.
