cumstance especially distinct in the form of the body 
and the situation of the dorsal tin. The fins are some- 
what damaged; but the length to the tip of the lower 
caudal lobe was probably almost 23 cm. The length 
of the body (to the end of the middle caudal rays is 
199 mm. Greatest depth 32*2 % of the length of the 
body, least depth 9'5 % of the same. Greatest thick- 
tin 17*1 %, of the length of the body. Pectoral tins 
equal in length to the base of the anal tin, ventral 
fins 15 7 2 % of the length of the body. Distance be- 
tween the latter fins and the tip of the snout 87'2 % 
of that between the dorsal tin and the same point. 
Length of the middle caudal rays 7*5 % of that of 
the body. Above the lateral line 10 scales, below

ness 39 % of the greatest depth. Length of the head 
21*1 % of that of the body, postorbital length of the 
head 47'6 % of its entire length. Distance from the 
tip of the snout to the beginning of the dorsal tin 
51 '3 %, base of the dorsal tin L 2*3 %, of the length 
of the body. Distance from the tip of the snout to 
the beginning of the anal tin 62‘2 %, base of the said 
it 6, in an oblique transverse row from the inser- 
tion of the ventral tin. Scales in the lateral line 47. 
Fin-formula identical with that of the preceding 
hybrid. 
This latter hybrid is thus distinguished from the 
White Bream mainly by a thicker body and a shorter 
anal fin.
