Mr. Gr. C. Crick, A.R.S.M., F.G.S., gave an account of some 

 recent researches on the belemnite animal. He stated 

 that it was not his intention to deal that evening with the 

 homologies of the belemnite shell or with the phylogeny of the 

 belemnite group, but to confine himself to the restoration of a 

 t3qDical belemnite animal and its shell, as shown particularly by 

 examples in the British-Museum collection. 



He first demonstrated, by means of a rough model, the construc- 

 tion of the belemnite shell, including the guard or .rostrum, the 

 phragmocone with its ventrally-situated siplmncle, and its thiii 

 envelope the conotheca, with its forward prolongation and expan- 

 sion (on the dorsal side) known as the pro-ostracum. He then 

 exhibited photographic slides of examples in the British-Museum 

 collection showing these various characters, and noted the abrupt 

 termination of the chambered cone on the lower part of the pro- 

 ostracum, of which the dorsal surface may have been partly or 

 almost completely covered by a thin forward extension of the 

 guard. To illustrate what was known of the complete body of 

 the ainimal as found associated with the guard, he then showed 

 photographic slides of two of tlie examples figured by Huxley 

 in his ' Memoir on the Structure of the Belemnitidie ' published in 

 1864. Each of these exhibited the guard associated with portions 

 of the pro-ostracum, the ink-bag, and the booklets of the arms. 

 The form of the booklets with their thickened bases was discussed, 

 this feature in a great measure justifying the attribution to the 

 belemnite of certain cephalopod remains (found practically at 

 about the same geological horizon) that included uncinated arms 

 associated with an ink-bag, and frequently also with nacreous 

 portions of (presumably) the pro-ostracum. 



Of the remains of uncinated armed cephalopods from the Lias, 

 each exhibiting the same form of booklets as those figured by 

 Huxley, he said that the British-Museum collection contained 

 seventeen examples, all from the neighbourhood of Lyme Regis 

 and of Charmouth, in Dorset. Each specimen exhibits a number of 

 uncinated arms associated usually with an ink-bag, sometimes also 

 with nacreous matter, and in two instances also with the guard or
