Paper, 'On the bone in crocodilia commonly regarded as the os pubis and its representative among extinct reptilia' by Harry Govier Seeley

Description

Seeley writes: 'Normally three elements enter into the construction of the pelvic girdle, each of which unites with the other two, and contributes to the formation of the acetabulum for the femur. The ilium and ischium are always more or less ossified, but sometimes the pubis remains represented by cartilage throughout life. Among the Amphibia the pubis is often in this cartilaginous state in its living representatives, so that only two bones and a cartilage usually contribute to form the articular cup for the femur. Among Urodeles the pubic cartilage is perforated by a foramen, which corresponds with the foramen in the ossified pubis of a lizard, and appears to carry the obturator nerve; so that its identification with the pubis is established.'

Annotations in pencil and ink. Includes one figure of the pelvic cartilage of Crocodylus palustris [mugger crocodile].
