lost, I am enabled at least to present a very good idea of the 
shoulder girdle in this fish. This is shown in Fig. 12, illus- 
trating this paper, and if the reader happen to have at hand a 
copy of my osteology of Amza calva, published in the Annual 
Report of the Commissioner of Fish and Fisheries for 1883, it 
will be well to compare it with the figure I there gave of the 
shoulder girdle of MWicropterus salmoides (Pl. 14, Fig. 35). It 
represents these parts as they appear in a typical teleostean 
fish. A glance is sufficient to satisfy us that the general form 
of the proscapula (Ps) of Grammicolepis is very much like that 
element in the Bass, differing principally in being slenderer and 
more sloping, and in its relations with some of the other bones. 
I am very sorry that I have not at hand the shoulder girdle of a 
Caranx, as it would be interesting to compare it in the present 
connection. 
As is most usual in teleosteans, the hypercoracoid and hypo- 
coracoid (Fig. 12, yp.c. and Hyo.c.) are fused together, and in the 
present instance, to the proscapula also. The hypercoracoid 
(Hyp.c.) is pierced by the usual foramen seen in this element 
among typical teleosts. The anterior projection of the hypocor- 
acoid (//yo.c.) is long and slender, almost reaching to the extrem- 
ity of the proscapula (Ps). 
It will be noted in Fig. 12 that each of these elements 
develop a backward, extending process, and the letters /Zyp.c. 
stand between them. This recess harbors the actznosts of the 
pectoral fin, when these parts are zz sztu. These pectoral fins 
have been carefully wrapped up by Professor Poey in a separate 
little package, and I find three of these actinosts attached to 
each fin. It does not appear as though any of them had been 
lost, and I am led to expect that that is the correct number in 
life. They are composed of rather elementary bone, as is so 
much of the rest of the skeleton in this curious fish. Now the 
bone marked 7 in Fig. 12 I take to be the ¢eleotemporal, and 
designated by the same letter in my drawing of the shoulder 
girdle of the Black Bass. On this latter form, however, as it is 
also in Amza, the teleotemporal is very loosely attached to the 
rest of the girdle by ligament, while here in Grammtcolepis, it is 
represented (7) by an exceedingly long and slender bone, which 
has its superior extremity moulded upon the side of the pro- 
scapula s, and firmly attached thereto. I fail to find in any of
