i 9 4i CATALOGUE OF FISHES OF TORTUGAS H3 



This species is quite distinct from P. cruentatus. Its fin formulas generally are 

 D. X,i4 or 14V2 ; A. HI, 14/2 or 15%- It has about eight fewer rows of scales be- 

 tween the anal origin and the lateral line, counting the series in the usual way. 

 Gill rakers 22 or 23 on lower limb of first arch. 



Tropical Atlantic, occasionally drifting northward to Cape Cod. S. F. H. 



Pseudopriacanthus altus (Gill) 



One specimen, 22 mm. long, was taken in 12 to 15 fathoms. 



Color reddish, with three clear-cut dark bars fading in alcohol; spinous dorsal 

 and anal black, this color extending also on base of soft fins; distal parts of these 

 fins and entire pectoral and caudal colorless; ventrals black, their inner margins 

 attached to belly almost to anus, not free as shown in Goode and Bean's figures 

 (Ocean. Ichthyol., 1895, pi. 46, figs. 239, 240). W. H. L. 



A second specimen is listed in Dr. Longley's notes, taken in 45 to 50 fathoms. 

 The collection contains a specimen 50 mm. long, without definite locality label, 

 which may be that fish. This species, then, seems to be rare in the vicinity of 

 Tortugas. 



The following enumerations and proportions are based on the 50-mm. speci- 

 men from Tortugas: D. X,n; A. Ill, 10; scales 47; gill rakers 20. Head 3.4; depth 

 1.65. Eye in head 2.0; snout 5.45; interorbital 4.3; maxillary 1.6; pectoral 2.0; 

 ventral 1.1. 



The narrow preorbital and the preopercle are serrate; the spine at the angle 

 of the latter is scarcely enlarged. The pectoral fins are short and rounded, but 

 the ventrals are long, reaching base of first soft ray of anal. 



Dr. Longley has the following on the larger specimen taken by him: "Red- 

 brown, iris redder than body." 



West Indies, and northward in the Gulf Stream. S. F. H. 



Family PEMPHERIDAE. Deep-Water Catalufas 



Pempheris schomburgkii MiAller and Troschel 



Pempheris schomburgkii Miiller and Troschel, in Schomburgk, Hist. Barbados, 1848, 



p. 669 — Barbados. 

 Pempheris mulleri Poey, Memorias, vol. 2, i860, p. 203. 



No account of this species was found in Dr. Longley's manuscript, and it 

 appears to be mentioned only a few times in his field notes. In his copy of Jordan, 

 Evermann, and Clark's Cheeky list (1930, p. 323) he definitely assigned Pem- 

 pheris mulleri Poey to the synonymy of P. schomburgkii, as shown above. 



Dr. Longley stated in one entry that he noticed these fish in small schools 

 among coral heads three days in succession. They were markedly transparent, 

 the whole axial skeleton back of the abdominal region being visible; body cop- 

 pery; distinct red line at base of anal. On account of the method of operation of 

 the pectoral fins, which vibrated quickly, the fish moved with peculiar starts in
