472 REPORT OF COMMISSIONER OF FISH AND FISHERIES, 
every day. The darker specimens are called by the fisherman Ronco 
prieto, the paler ones Ronco blanco. While in Havana, Professor Jordan 
took especial pains. to select specimens, representing every variety of 
form and coloration in this species. In the very large collection secured 
we find specimens answering fairly to Poey’s serratum, albidum, acutum, 
as well as other specimens variously intermediate. A typeof Haemulon 
acutum sent by Poey to the U. 8. National Museum is identical with this 
species, as iS also the type of H. chromis Cuy. & Val., preserved in 
the Museum at Paris. The original type of Desmarest’s Diabasis parra 
is still preserved in the Museum at Paris. It belongs to the present 
species, fur which it is the oldest name.

Hemulon scudderi Gill, Proc, Ac. Nat. Sei. Phila. 1862, 253 (Cape San Lucas); Stein-

Diabasis scudderi Jordan & Gilbert, Bull. U. S. F. C. 1881 Seer 1882 (107, 110)

(Cape San Lucas, Panama). 
Hemulon brevirostrum Giinther, Fishes Centr. Amer., 1869, 418 (Panama). 
Hemulon undecimale Steindachner, Ichth. Beitr. 111, 1875, 11 (Acapuleo, Panama). 
Habitat: Pacifie coast of tropical America, Guaymas to Panama. 
Etymology: Named for Samuel H. Scudder. 
This species is the Pacific representative of Hemulon parra. It 
reaches a similar size, is equally abundant, and passes through a simi- 
lar range of Variations and coloration. Most of the species collected 
by Prof. Gilbert at Mazatlan and Panama have 11 dorsal spines and 
correspond to the Hamulon undecimale of Steindachner. Two or three 
of them have, however, 12 dorsal spines, as in the original types of 
H. scuddert and H. lanes um. We are unable to detect any other 
difference of importance among these specimens, and refer all to H. 
scudderi,regardin g it as a Species with the number of spines indifferently 
it ord? sNo other species of Hamulon ever has fewer spines than 12. 
If these should finally prove to be. specifically distinct, the form with 
11 spines should stand as Hemulon undecimale, that with 12 spines as 
Hamulon scudderi. 
Specimens are in the museum at Cambridge from Lower California, 
Acapulco, and Panama. The three specimens from Acapulco have D, 
XII, those from Panama (types of H. wndecimale) have D. x1. 
39. HAAMULON CARBONARIUM. (Ronco Carbonero.) 
Hemulon carbonarium Poey, Memorias de Cuba, 11, 176, 1860 (Cuba); Poey; Synopsis, 
1868, 318; Poey, Enumeratio, 44, 1875; Taeien desea l.c., 298; Jordan, 
1. c., 1890, 319 (Bahia). 
‘Habitat: West Indies, south to Brazil. 
Etymology: Carbonarius, coaly, an allusion to the common name. 
This species is common at Havana, where it is known as roneco car- 
bonero. It reaches a length of about 10 inches. We have examined
