1941 CATALOGUE OF FISHES OF TORTUGAS j^ 



I have seen a single adult and no young. Jordan and Thompson (Bull. U. S. 

 Bur. Fish., vol. 24, 1904 (1905), p. 248) also reported 1 specimen. 



Metzelaar's figure (Trop. atl. Vissch., 1919, p. 93, fig. 28) of the young of 

 Holacanthus tricolor at 39 mm., and examination of Poey's 22-mm. type of 

 Sarothrodus ataeniatus (Mus. Comp. Zool. no. 16251), make it possible to assign 

 Poey's species to the synonymy here, for it is, except for size, the same as Metze- 

 laar's specimen. The spine at its preopercular angle and its ocellus are both very 

 clear. 



Atlantic coast of tropical America, northward to Florida and Bermuda.

Holacanthus ciliaris (Linnaeus). Queen angelfish 



Chaetodon ciliaris Linnaeus (part), Syst. nat., 10th ed., 1758, p. 276 — Indies. Bloch, Natur- 



gesch. ausland. Fische, vol. 3, 1787, pi. 214. 

 Chaetodon squamulosus Shaw, Naturalist's miscellany, vol. 8, 1796, p. 275 (after Catesby). 

 Chaetodon parrae Bloch and Schneider, Syst. ichth., 1801, p. 235 — Cuba (after Parra). 

 Holacanthus cornutus Desmarest, Mem. Soc. Linn. Paris., vol. 2, 1823, pi. 3, fig. 3 — Cuba. 

 Holacanthus jonnosus Castelnau, Anim. Amer. Sud, Poiss., 1855, p. 19, pi. 11, fig. 2 — 



Bahia. Giinther, Cat. fish. Brit. Mus., vol. 2, i860, p. 47. 

 Pomacanthus ciliaris Jordan and Gilbert, Bull. U. S. Nat. Mus., No. 16, 1883, p. 615. 



Only 1 fully grown specimen and 2 young were seen in the course of much 

 work on the reefs. 



The ocellus with dark blue center on the nape, the general richness of colora- 

 tion, to which the submarginal dark blue of the vertical borders of dorsal and 

 anal fins contributes much, and the completely yellow caudal fin are distinguish- 

 ing marks of the species in the field. 



Holacanthus lunatus Blosser (Ann. Carnegie Mus., vol. 6, 1909, p. 299) has 

 been placed by me in the synonymy of Angelichthys isabelita, but incorrectly 

 (Carnegie Inst. Wash. Year Book No. 31, 1932, p. 300). Blosser's plate indicates 

 that his 19-mm. fish is the young either of that species or of H. ciliaris, and the 

 fin formulas he gave (D. XIV,i8; A. III,i8) fit the former. His count, however, 

 is inaccurate, as the formulas actually are, D. XIV,2i; A. IIL21; P. 17 or 18, or 

 the dorsal spines may be 1 less and -the soft rays 1 more, as the last spine or first 

 ray is broken. There is then little doubt that H. lunatus is a synonym of 

 H. ciliaris. W. H. L. 



The following is from Dr. Longley's notes: "The queen angel has a distinct 

 ocellus at nape, entire tail yellow, dark blue on anterior base of pectoral and on 

 inner webs of dorsal and anal fins, same color as in the ocellated spot on nape. 

 Much the yellowest of the local species, and its rich color is heightened by an 

 orange stripe at the base of the dorsal beginning at the nape." 



The Tortugas collection contains 3 specimens, respectively 30, 34, and 83 mm. 

 long. The largest one is in the transition stage, with respect to color, from the 

 young to the adult as described by Dr. Longley. The 2 smaller ones retain the 

 dark bars and much of the other color of the juveniles.
