of extending the expansion of the osseous frame for the support of the hymeneal 

 swellings. There is a marked inward bending of the posterior half of the ilium 

 without any corresponding eversion of the ischium, and the acetabula are thus 

 thrown more inwards towards the mesial line, and by these modifications, which 

 are most marked in the female pelvis, the span of the pubic arch and the expan- 

 sibility of the surrounding parts are considerably reduced, and the outlet of the 

 pelvis to that extent that it seems improbable that it could permit of the discharge of 

 the young of the size given birth to by Macaques of the dimensions of M. cyclopis. 



Dr. Murie also describes the ilium as anteriorly overriding the sacrum far 

 more than is ordinarily the case, i. e., that the sacrum is projected into the pelvis. 

 This condition would seem to be analogous to that deformity of the human pelvis 

 arising from insufficient strength of its walls,^ in which the sacrum is projected into 

 the outlet of the pelvis, and the acetabula (as before described in M. cyclopis) 

 approach the middle line, while the pelvic bones are pressed forwards and down- 

 wards between them. 



Such considerations as the foregoing would seem to indicate that the 

 conditions of these pelves may have a different explanation than that given by 

 Dr. Murie. 



Dr. Gray, in the appendix to his Catalogues of Monkeys,^ compares M. sancti- 

 Johannis to M. cyclopis, but the origin of this comparison I have explained under 

 Jf. sancli-johannis.
