first arch: scales with about 15 to 24 apical serrae. 
We compared a large series of all ages of the closely 
related B. tyrannus (Latrobe) in the Academy, from Massachus- 
sets, New Jersey, Delaware, Marlyend, North and South Carolina, 
Wetar oho: Teas of to 3 1/57 depth 2 2/6 to 5 1/5; BD. Iv 
16, varies frequently 15, 17 or 18 branched rays; A. iii, 
I9, 1, varies frequently in branchrd rays 17 or 16, seidom 
20, rarely 16 or 21; scales in dedian lateral series usually 
50, vary 45 to 77, fewer in young end often more in adult; 
5 to 8 scales on caudal base; 23 scales transversely at 
dorsal origin, frequently 25, vary sometimes 21 to 24 or £6 
to 28; predorsal scales 30, frequently 33, 34, 36 or 41, 
eften 31, S52, 55 or 356, seldom 26 to 29, 37, 39 to 40 or 45; 
snout 3 2/5 to 44 in head from upper jaw tip; eye 3X to 64; 
maxillary 2 to 2i; interorbital 3 4/5 to Az: serrae 19, fre- 
quently 20, often 18, seldom 17, rarely 21 or 22 - 13, frequently 
12, often 14, seldom 11; length 60 to 356 mm. A New Jersey 
example 250 mm. Shows about 70 Gill-rakers on ceratobranchial 
of first arch, compared with 80 - 140 @ill-rakers usually 
counted. Sceles with 30 to 40 apical serrae. 
These comparisons are made as the limits of distribution 
of the two species have not yet been given. It is thus likely 
that B. pectinatus occurs northward to Rio Janeiro. The study 
of much Brazilian material is necessary, however, before the 
above characters may be shown to be definite.
