rudimentary phalanges ; each of the other fingers (not 

 including the thumb), having three. This rudimentary 

 index finger has no nail ; there is simply a minute mark- 

 ing, like a cicatrix, or rather a mere short, depressed, 

 smooth line, an indication of where a nail should be. 

 The nails of the thumb and other fingers are all thin, 

 flat, and rounded or ovate, like those of the human hand, 

 and are not extended beyond the points of the fingers. The 

 remaining three fingers are slender and prolonged, and the first 

 phalanges are all conjoined by the integuments, the two distal 

 phalanges of each finger alone being free. The index or second 

 finger (considering the thumb as a finger) is, as already describ- 

 ed, merely like a tubercle rising at the base of the others. The 

 third finger is the smallest of the other three fingers, and also 

 the shortest ; the fourth (or middle of the developed fingers) 

 is the longest ; and the fifth, or last, is longer than the third. 

 The hands are each divided into two opposing portions : the 

 thumb, with the tubercle at its base, being opposed to the other 

 fingers with the tubercle-like index at their base ; the thumb 

 itself being opposed to the fourth, the middle or longest of the 

 fingers. 



The posterior hands or feet (see fig. 2, which also shows 

 the length of the tarsus) are rather larger and stronger than 

 the anterior ones, and are each divided into two opposing por- 

 tions ; the one consisting of the thumb, with a large, rounded, 

 fleshy tubercle projecting from the inner side of its base, as in 

 the fore hand ; and the other portion, formed of the remaining 

 four fingers, the first phalanges of which are also conjoined, 

 being covered by the integuments, as in the hand. There 

 is a comparatively smaller fleshy tubercle, somewhat like the 

 undeveloped index finger of the fore hand, projecting from the 

 outer side of their base, which is opposed to the tubercle at 

 the base of the thumb. It is not supported by any bone, but 

 is merely a horny and fleshy projection like that on the base 

 of the thumb. The nails of the thumb and fingers are thin, 

 flat, and rounded or ovate in form, like those of the fore hand, 

 with the exception of that of the second finger (counting the 

 thumb as the first), which is narrow, convex, sharp-pointed, and 

 claw-like, and extends nearly to the point of the third finger,
