Stromateus xantlilirilS (Quoy & Gaimard). One specimen. Rio 



Janeiro, Brazil. D. IV, 39 ; A. Ill, 37. 

 Holocentrum peiltacantllUS Bloch. One specimen; Rio Janeiro. 



D. XI, 16 ; A. IV, 11. Lat. 1. 45. Depth 3 ; head 3|. Interorbital 6 in 



head. 



Centropom US nil decimalis (Bloch). One specimen. Sao Matheo. 

 Centropristis striatiis (L.). One specimen. Loc. ? 

 CrenyatrenillS cavifrons (C. & v.). One specimen. Brazil. 

 LilltsanilS JOCU (Bloch & Schneider). One specimen. Braret. 

 Calamus calamus (C. & V.). One specimen. St. Thomas, W. I. 

 Crj'ptotomus UStUS C. & V. One specimen. Rio Janeiro. 



Harpe naevius sp. nov, 



A dark spot as large as eye at the distal ends of the three upper pectoral 

 rays. First dorsal spine and its membrane black ; second dorsal spine and 

 all but the margin of its membrane black ; base of the third spine black ; a 

 very narrow margin of the soft dorsal dusky. A rusty spot above and in front 

 of the pectoral just within the gill cover. Color otherwise (in alcohol) yel- 

 lowish. D. XII, 10^; A. Ill, 12^. Scales 5—33—10; head 3| ; depth 3. 

 Pectorals broad, rounded, l^^^ in head ; first ventral ray prolonged, reaching 

 anus. Soft dorsal, anal, and caudal as in H. rufa. Head as in rufa. Ante- 

 rior canines f f . Upper posterior canine stronger than lower. Profile slightly 

 convex, preopercle finely serrate. Eye 5 in head. 



One specimen (No. 1263), 210 mm. Rio Janeiro. 



Pachyurus scbomliurgkii Griinther. 



D. X, I, 31^ ; A. II, 7^^. Eye 3^ in head. A dusky blotch before dorsal, 

 dorsals spotted, the upper half of the spinous dusky. Sides of body with 

 larger spots. Caudal thickly scaled to its tip, soft dorsal with fewer scales 

 on its basal four-fifths. Teeth well developed in both jaws. Spines of angle 

 of preopercle much enlarged, flat. 



One specimen, 215 mm. Para (1911). 



In squamation this specimen agrees well with the original descrip- 

 tion of schomburgkii; it has, however, more dorsal rays. Stein- 

 dachner's figure of P. nattereri is evidently intended for the same 

 fish. The squamation of the head is not well reproduced. 



Pachyurus squamipinnis Agassiz. 



Preopercular angle prominent, the spines at this point scarcely larger than 

 those of the vertical limb. Gill-rakers longer than broad, 6 -\- 10. Longest 

 dorsal spine 2 in head. Anal spine strong 1§ in head. D. X, I, 24| ; A. II,
