to each of the toes ; in Macalister's specimen to the four outer 



toes onlj. 



The following muscles were present and agreed with 

 MacaHster's description -.— Tensor vagince femoris (text-fig. 16, 

 t.v.f.). Gluteus maximus (text-fig. 16, gl.wx.). Agitator caudo' 

 (text-fig. 16, ag.cd.). Gluteus medius-\- minimus (text-fig. 16, gl.m.). 

 Pyriformis (text-fig. lQ,py.). Quadratus femoris (text-fig. 17, q.f.) 

 Sem'imemhranosus (text-figs. 16 & 17, sm.). Gracilis (text-fig. 17, 

 gr.). Pectineus (text-^g. 17, pt.). Vastus externus (text- fig. 1 6, v.e.). 

 Vastus internus (text-fig. 17, v.i.). Psoas parvus (text-fig. 17, p.p.). 

 lleo-psoas (text-fig. 17, il.p.). uidductor primus (text-fig. 17, add. l). 

 Popjliteus (text-fig. VJ, pop.). Tibialis posticus (text-fig. 17, t.p.). 

 Extensor Jialhicis longus. Flexor profundus (text-fig. 17, p.p.)- 



In this review of the muscles, it will be noticed that in several 

 particulars this specimen approaches Dasypus more nearly than 

 those dissected by Macalister and Hyrtl. One may take as in- 

 stances : — The extensive origin of part 2 of the latissimus dorsi. 

 The twofold nature of the splenius capitis. The want of a clavi- 

 cular origin to the ])ectoralis major. The absence of a dii'ect 

 insertion of the plantaris to the heel, and lastly the mode of origin 

 of the peronei — an origin, so far as I know, hitherto found only in 

 Dasypwi. 



Joints. 



Temporo-maxillary joint. — This is of a very feeble character with 

 small flattened articular surfaces. It is remarkable for the absence 

 of an interarticular fibro-cartilage. Parsons \ in his Hunterian 

 Lectures on Mammalian joints, records three examples of temporo- 

 maxillary joint among the lower orders of mammals without an 

 interarticular cartilage (e. g. Ornithorhynchus, Dasyurus, and Dasy- 

 pus). It is interesting to find that Clilamydophorus shares this 

 exceptional character with Dasypus. 



Shoulder-joint. — There is a stout accessory ligament that passes, 

 superficial to the capsule, from the coracoid process downwards 

 and backwards to the outer sui-face of the head of the humerus. 

 This ligament is noticed by Hyrtl, and can still be seen attached 

 to his preparation of the skeleton (E.G. S.Osteol. Series, No. 3582), 

 and I only mention it to draw attention to a similar ligament in 

 Dasypus and Tattisia(R. C S. Physiol. Series, Nos. B 125, B 126). 



The Visceea. 



On the coarse anatomy of the viscera there is little to be said, 

 for this subject has been dealt with in detail by Hyrtl, and any 

 gaps left in his descriptions have been filled by Macalister and 

 Watson-. I shall thus mainly confine my remarks to certain
