deep, resembling in this respect the corresponding part of the 

 pelvis of the Bintnrong. The ischial tuberosities were little 

 developed, as in the Ichneumon, and there is but slight indica- 

 tion of the ischial spine. 



The femur, figure 33, is relatively stout and has a straight 

 shaft. The hemispherical head is set upon the shaft by a 

 short, thick neck, and the fovea capitalis for the terete liga- 

 ment is distinct. The trochanter major rises to the level of 

 the head, and the digital fossa is deep, narrow, and slit-like, as 

 if it had been compressed from before backwards, as in certain 

 of the carnivorous Marsupials, notably the Dasyures and Opos- 

 sums. The trochanter minor is broad and placed upon the 

 inner side of the shaft just below the neck. The distal end of 

 the bone is characteristic, being relatively broad and flat. The 

 condyles are well separated and have comparatively little poste- 

 rior extension ; they are sub-equal in size, and the inner is not 

 produced downwards to any perceptibly greater extent than 

 the outer. The rotular groove is broad and shallow and has 

 but slight upward extension upon the anterior surface of the 

 shaft. In all its characters, with the exception of the third 

 trochanter and the large size of the trochanter minor, the 

 femur bears a very strong resemblance to that of the Bintu- 

 rong, and differs from the viverrine and herpestine representa- 

 tives in the character of the distal end, the shape of the greater 

 trochanter, and the position of the lesser, which is more on the 

 inner border of the shaft. The patella, figure 35, moreover, is 

 short, flat, thin, and scale-like, having more the shape of that 

 of the Bintnrong, in marked contrast to its narrow, elongate, 

 thickened form in the other sections of the family. 



The tibia, figure 3i, does not closely resemble that of any 

 of the living Viverridse on account of the preponderance of 

 primitive characters which it possesses. These are seen in the 

 relatively small size, the slender and rounded shaft, its great 

 lateral curvature, and the small development of the . cnemial 

 crest. The head has the appearance of being flattened from 

 before backwards ; the two tuberosities have the usual form, 

 but the spine is very much less divided than in the modern 

 species. The entire form is quite as much like that of the 

 Marsupials as that of the living types. Near the middle of 

 the shaft or what may be taken as the extreme lower end of 

 the cnemial crest is seen a prominent roughened area for 

 tendinous attachment. This area is also pronounced in the 

 tibia of many Marsupials ; and is likewise present, but less 

 strongly marked, in the Bintnrong. If it served for the 

 attachment of the tendon of one of the inner hamstring 

 muscles, which is in all probability the case, it indicates an 

 unusually low position for this insertion. A short distance 

 above, and to the inner side, is seen the point of insertion of
