been crushed and broken into several fragments, and has 

 lost the extremity of the inner trochanter, agrees approxi- 

 mately in size with that of /. mantelli {e.g. No. 2650, 

 supra, i. p. 223) ; its total length being 0,880 (32 inches). 

 The convexity of the shaft and the obliquity of the head 

 are well shown. The length from the upper extremity of 

 the intercondylar fissure to the interval between the 

 greater trochanter and the head is 0,644 (25*5 inches).

R. 1632. Ten associated imperfect sacral and caudal vertebrae ; from 

 Hollington quarry. These specimens were obtained a short 

 distance from the preceding, and almost certainly belong 

 to the same individual ; they are noticed by the writer in 

 the * Quart. Journ. Geol. Soc' op. cit. p. 40. The sacrals, 

 which have flattened haemal surfaces and were not anchy- 

 losed together, precisely resemble those of No. E. 811 

 (infra). Dawson Collection. Purchased, 1889. 



R. 1632 a. Three imperfect and much crushed cervical vertebrae 

 and the distal portion of a metatarsal, associated with the 

 preceding. The cervicals resemble those of R. 33.

R. 1632 b. The terminal phalangeal of the second digit of the left 

 pes, associated with the preceding. Dawson Collection. 



R. 604-811. These specimens (supra, i. pp. 198, 199), which came 

 (Fig.) from the Hollington quarry, are referred to this species 

 on account of their resemblance to the preceding, and also 

 on the ground that the undermentioned ilium is different 

 from that of i". dawsoni. The left ischium is figured in 

 Part I. p. 199, in association with the ilium of the latter 

 species. The dorsal vertebrae agree with those of No. 

 R. 1148. 



R. 811 b. The imperfect and crushed left ilium, associated with the 

 preceding specimens ; from Hollington quarry. Noticed 

 by the writer in the ' Quart. Journ. Geol. Soc' vol. xlvi. 

 p. 42 l . The extremities of the preacetabular and pubic 

 processes are wanting, and the postacetabular portion is 

 imperfect. The preacetabular process differs from that of 

 I. dawsoni in the absence of an inner extension. Com- 

 pared with the ilium of i". Jittoni, this specimen differs by 

 the shallower preacetabular process, the longer interval
