M.E. F. E. BEDBABD ON THE ANATOMY 



[Mar. 1, 



crucial sulcus, which is situated rather far forward. This part of 

 the gyrus is perfectly smooth, there beiog no precrucial sulcus.

Bvain of Bassariscii^ asf^iius. 



Posteriorly to the crucial sulcus the sagittal gyrus, as is the case 

 with the corresponding gyrus in other Arctoids, is marked by two 

 fissures : one of these starts from the angle of the parietal sulcus 

 and runs for a short distance anteriorly ; the other is shorter and 

 lies to the outside of it and is unconnected with any other furrow. 



The anterior recurrent portion of the sagittal gyrus is much 

 narrower than I have seen it in any Arctoid, not even excepting 

 the smaller Ictonyx. 



§ Alimentary Canal. 



The jyalate was, as has been already mentioned, somewhat 

 diseased posteriorly : I am not, therefore, able to be certain as to 

 the arrangement of the ridges in this region. Li the anterior part 

 of the palate, just behind the incisor teeth, ^^ere three triangular 

 cushions, their apices converging posteriorly. Immediately behind 

 and springing from the interval between the canine and the first 

 premolar is a ridge which does not meet its fellow in the middle 

 line. Then come four complete ridges springing from the basis of 

 the teeth, of which the first is very much more concave (backwards) 

 than those which follow. 



The stomach of the animal is not greatly elongated. It is, per- 

 haps, slightly more globular than that of ^larus fulgens, figured 

 and described by Sir W. Elovver \ Its length when distended was 

 3 inches, by a greatest diameter of 2 inches. The omentum, loaded 

 \\ith fat, is not attached accurately along the greater curvature of 

 the stomach. It is so attached for, perhaps, the first third of that 

 curvature ; afterwards it takes, so to speak, a short cut to the basis 

 of the oesophagus, the line of its attachment being still curved and 

 parallel to that of the greater cui-vature.
