from nape vertically through eye, across cheek, and thence just above ventral 

 outline to base of and on ventral fin; the second wider, crossing body between 

 first 3 dorsal spines and space between ventral axil and pectoral origin; the third 

 just before base of caudal. W. H. L. 



In addition to the specimens listed, another one, 35 mm. long, is mentioned in 

 Dr. Longley's notes. This small specimen was taken at a depth of 40 fathoms. 



Fowler (Proc. Acad. Nat. Sci. Philadelphia, vol. 86, 1934, p. 356, fig. 8) recog- 

 nized a new species, which he named Antigonia browni, based on a specimen 

 68 mm. long, taken off the coast of New Jersey in 70 fathoms. The 4 small speci- 

 mens (40 to 67 mm. long) in Dr. Longley's collection agree well with Fowler's 

 description and figure of A. browni. If A. browni actually is distinct from the 

 cosmopolitan A. capros (which would seem to require the study of more and 

 larger specimens for positive determination), the Tortugas material apparently 

 should be referred to A. browni. The body is quite as deep in the Tortugas 

 specimen as in the fish from New Jersey described by Fowler, but the pectoral 

 is scarcely as long as represented in Fowler's figure. Fowler described and figured 

 two dark crossbands, whereas Longley described three (in a specimen 75 mm. 

 long), the one at the base of the caudal being missing in Fowler's specimen, as it 

 is now in Longley's preserved specimens. It is possible, then, that in long- 

 preserved material the other bands may fade also, which would remove one of 

 the supposed differences. In the Tortugas specimens, as in the New Jersey fish, 

 the 2d dorsal spine is proportionately much longer and stronger than shown in 

 Goode and Bean's figure (Ocean. Ichthyol., 1895, p. 229, fig. 235), and scales are 

 present on the interradial membranes. 



The following proportions and enumerations are based on the specimen that 

 furnished the basis for Dr. Longley's color description: Head 2.6; depth 0.82; 

 pectoral 2.4. Eye in head 2.85; snout 4.3; interorbital 3.9; longest dorsal spine 

 1.05. D. VIII,32; A. III,3i; scales about 58, 4 rows on cheek. 



Antigonia capros has been reported from deep water from many parts of the 

 world. S. F. H.

 Chaetodon bricei Smith, Bull. U. S. Fish Comm., vol. 17, 1897, p. 102, fig. — Woods Hole, 

 Massachusetts (young). 



Occasional; singly, in pairs, and rarely more. Less common than Chaetodon 

 ocellatus, more common than C. striatus. The young, of 25 mm., once were taken 

 on the grass flats near Long Key or Bird Key reef. The adults are reef fishes; 

 very frequently found about the greater coral heads. 



Usually seen in a very pale olivaceous ground-color phase, with black ocular 

 band, and ocellated black spot larger than the eye under the soft dorsal, occa-
