CRYPTOTHIRIA BALANT. 269 
Mr. Goodsir’s figures were more or less perfect repre- 
sentations of the mass that we had observed. 
The young, which we have frequently taken in an 
incomplete stage, are developed as in true Isopoda; and 
the earliest larval condition, as figured by Goodsir and 
Rathke, shows that the animal is, both in its develop- 
ment and parasitic habit, closely allied to the Bopyroid 
crustacea. 
The animal represented in the middle of our wood- 
cut, which we consider to be the male, corresponds, so 
far as the head and anterior segments of the body are 
concerned, with that which Mr. Goodsir has figured as 
being the anterior segments of his supposed male, and, 
if Mr. Goodsir’s dissections be true, appears to offer a 
very considerable evidence of the near relation of the 
two animals. But we were inclined to think that 
Mr. Goodsir’s figures, 1—38 in pl. 3, which he gives as 
the concealed cephalic portion of what he calls the male 
of the Balanus, and the entire dorsal view of the same 
animal given in pl. 4, fig. 10, were taken, the former from 
the real male, and the latter from the female, Liriope.* 
Though frequently having taken the females in con- 
nection with the Balanus, and these also charged with 
ova in various stages, we have never taken the male asso- 
ciated with the female, as is almost invariably the case 
with the other genera of the Bupyride. In this species 
* Tn the elaborate memoir of Dr. Buchholz above referred to, published 
last September, the learned author has arrived at an opposite conclusion rela- 
tive to the true condition of our supposed male, which he has carefully figured 
and described as the larva-form of the species, and which, in certain indi- 
viduals at least, becomes developed into the female, the fully developed con- 
dition of the male being still unknown. This observation completely supports 
the correctness of Goodsir’s statement, that his figures 1-3 represent the 
anterior articulated part of the animal of which a dorsal view is given in his 
figure 10, in which, however, the articulated portion is concealed by the 
swollen front of the second division of the body.
