24 MR. F. E. BEDDARD ON THE [May 2, 
I found it impossible to subdivide the Adductor mass. 
The Semimembranosus is divided into two muscles for some way 
in front of its obviously double insertion on to the tibia and the 
femur. I could not find, however, that this muscle was divided 
at its origin from the ischium, 
The Scmutendinosus, as in some other, but not in all, Mustelidee, 
has a very distinct caudal head. There is no Agitator ‘eaudee. 
The Zenwissimus is plainly present. 
The Zbialis anticus is single. 
§ Lungs. 
As Prof, Garrod pointed out in H. subauwrantiaca, the lungs in 
H. personata consist of four lobes on the right side and two on 
the left. Prof. Garrod, however, made no observations upon the 
relative sizes of the several lobes. On the right side the first lobe 
is rather larger than the second; the third is the biggest of all 
and quite twice the size of the first; the fourth or azygos lobe 1s 
the smallest of all. 
The two lobes on the left side are more nearly equal in size, but 
the second or lower lobe is the larger. 
§ Lier. 
The liver of this species appears to be much like that of 
H. subaurantiaca. The enormous right central lobe is deeply * 
fissured and exposes the gall-bladder on the diaphragmatic side. 
This lobe is quite twice the size of the left lateral lobe, which is the 
next largest ; this lobe again is larger than the right lateral, which 
does not show any great difference of size from either the left 
central or the caudate. The Spigelian lobe is minute. 
§ Pancreas. 
The pancreas of Helictis is almost exactly like that of the Tayra 
(Galictis), with which Arctoid I have specially compared it. It is 
not clear from Garrod’s description what is the precise form of the 
gland in the species investigated by himself. In H. personata 
there is a circular portion of the pancreas running right round the 
duodenal loop +; this ends in a straight piece running parallel 
with the spleen. The chief difference which Helictis shows from 
Galictis is in the mesenterial attachment of the straight part of 
the pancreas. In Galictis a transparent mesentery, apparently 
anangious, 1s attached to the whole length of the straight region 
of the pancreas, and is inserted on to the mesocolon along a 
line which commences in front of and ends behind the left kidney. 
* But not quite so deeply as in Galictis. 
+ As in many Carnivora, cf. e.g. Owen’s Comp. Anat. vol. ili. p. 496.
