chanter and the interior of the femur and tibia are minutely 

 shagreened ; the low flat granules of the hand are very 

 indistinct. Kather short and more or less dentatcd hairs are 

 abundant everywhere ; those of the fingers, wliich^ besides, 

 bear tactile hairs, are more slender and simpler. Tlie arrange- 

 ment of the tactile hairs (PI. YI. fig. 3 «) seems to be 

 similar in the two specimens : most conspicuous are two 

 placed very near to each other at the base of both fingers 

 exteriorly; two others are placed more distally on each finger. 

 Interiorly there are two close to each other near the base and 

 a single one distally ; dorsally there are a few. The ti^o- 

 chautcr, which has a long stalk, is distinctly longer than 

 broad ; its inner surface is evenly convex to near the tip; the 

 outer is suddenly convex, almost similar to a protuberance; 

 under this and separated from it by a longitndinal depression 

 there is a less-marked more even convexity, which is, perhaps, 

 the real exterior outline of the joint. The femur has no 

 marked stalk, is narrower than the trochanter, and about 

 4"5 times longer than broad distally ; it is gradually enlarged 

 distally ; the inner snrface is, after a shallow notch and low 

 elevation, almost straight; the outer is, beyond a basal short 

 concavity, almost straight proximally, but distinctly convex 

 distally. The tibia, which has a rather short and not very 

 well-marked stalk, is a little shorter and broader than the 

 femur ; the inner surface, beyond the distinct basal notch, is 

 almost straight ; the outer has a well-marked basal pronji- 

 nente and a low elevation where the stalk passes into the 

 joint proper ; between these two there is a shallow notch ; 

 the outline, beyond the above-mentioned elevation, is almost 

 straight and at last convex. The hand, which is as long as 

 but only 1"46 broader than the tibia, is slightly convex inte- 

 riorly, but almost straight exteriorly ; it is 2'5 longer than 

 broad, a little broader than it is high, and a trifle longer 

 than the fingers, which gape slightly when closed. Besides 

 the usual marginal row of teeth, which are rounded basally 

 and conical distally, the fingers bear accessory teeth, the 

 number and position of which differ in the two specimens 

 examined. The one (PL VI. fig. 3 a, a) had along the inner 

 side of the immovable finger eight teeth, of which the first 

 three near the middle were divided distally; the movable 

 finger possesses four inside. Exteriorly the immovable finger 

 bears about nine accessory teeth and the movable four; all 

 these are placed more or less near to the middle. In addition 

 to these teeth we find a number of organs (fig. 3 «, a) which 

 seem to bear some similarity to those described by Hansen 

 (15, p. 217). The other specimen differs from that described
