the inner tendinous band and tlie thickened inner strand of the 

 outer baud, but above the rest of the tendon. The tensor longus 

 tendon, as usual, dilates at the middle oE the patagium into a 

 yellowish thickened nodule of different appearance from the rest 

 of the tendon. From this, or from its immediate neighbourhood, 

 arise a few strands of tendinous tissue arranged in a fan-lilice 

 fashion, which become collected into a thin tendon running 

 obliquely across the patagium to be inserted on to the tendon of the 

 extensor metacarpi. One of the thin strands which make up the 

 patagial fan is directly continuous with the biceps slip. The 

 muscle in fact appears to end in this tendon, and not to be inserted, 

 as is more usually the case, into the tendon of the tensor longus. 



The bicejps is less fleshy than this muscle often is. The tendons 

 of origin and insertion are continued over the greater part of the 

 muscle as superficial tendinous sheets. The muscle has practically 

 only one head of origin, that from the coracoid ; there is, however, 

 what I believe to be the remains of the humeral head in the shape 

 of an attachment to the under surface of the pectoralis major. 



The deltoid has an insertion upon the humerus of no great 

 extent. It is attached to that bone for rather less than a third of 

 its length. 



The anconceus has a humeral head which is a somewhat narrow 

 tendon arising'close to the insertion of the latissimus dorsi. 



The expansor secuiidarionmi appeared to be totally absent. 



The pectoralis viajor is rather a thin muscle ; it is, however, for 

 a portion of its extent divisible into two layers. The superior 

 margin of the muscle, i. e. that furthest away from the carina 

 sterni, is largely tendinous. The insertion of the muscle on to the 

 crest of the humerus is tendinous throughout for about the last 

 eighth of an inch. 



The pectoralis minor is, as usual, a bipinnate muscle, but the 

 lower side is much wider than the upper. Its origin from the 

 sternum and the carina extends rather more than halfway down. 



The latissimus dorsi is as usual divided into two muscles, with a 

 branch going to the skin (not always present in birds). This is 

 the dorso-cutaneous of Eiirbringer. The last mentioned overlaps 

 the entire origin of the posterior half of the muscle and is 

 continuous with the origin of the anterior. 



The glutceus maximtis consists of two separate parts. In front 

 of the acetabulum is a not very wide (5 inch) strap-shaped band 

 about the same size as the sartorius, which it partly overlaps. Prom 

 the acetabulum to the very end of the ilium arises a sheet of 

 muscle which completely covers the underlying biceps, and is 

 inserted on to the fascia covering the leg from the knee to nearly 

 halfway down. 



The glutwus medixis is incompletely divided into two halves. 

 They run side by side, and are inserted each by a separate tendon 

 of insertion which are connected by a muscular part. 



The glutceus minimus is completely hidden by the last muscle ; 

 it is small and entirely fleshy and arises from the iUum only.
