the Toucan; the lateral ones extending along two thirds the length 

 of the sternum, the mesial ones about one third. 



" After this detail it is scarcely necessary to observe that in all 

 the important points of the internal structure the Touraco manifests 

 close relationship to the Scansorial order, and a marked deviation 

 from the typical structure of the Rasores, in which the superadded 

 lateral dilatations of the alimentary tube, the crop and cccca, are so 

 largely developed. 



" The same affinity is also shown in the nature of its parasitic 

 worms, — the Tcenice belonging to the species filiformis of Ru- 

 dolphi, so remarkable for the length and tenuity of the body, and 

 which has hitherto been met with only in the Psittacidce. 



" 1 had an opportunity in this instance of witnessing very satis- 

 factorily the mode of generation of the Taenia. Many separate 

 joints were found in the track of the intestines, which, when viewed 

 under the lens, were seen full of ova. Each of these joints contained 

 from thirty to thirty-three ova, of a subglobular form, and a sur- 

 face rendered irregular by minute asperities. The posterior joints 

 of the unbroken worms were similarly distended, and readily sepa- 

 rated. 



" This division of the body approximates to the fissiparous mode 

 of generation; but as the joints are merely the capsules of the ova, 

 it is more strictly analogous to the mode of generation in the 

 Lerncecp and Entomostraca." 



January 28, 1834-. — A preparation was exhibited of the stomach 

 of Semnopithecus Maurus, F. Cuv., presented to the Society by 

 G. H. Garnett, Esq. It was brought under the notice of the Meet- 

 ing for the purpose of showing that there exists in that Monkey the 

 extremely elongated and sacculated form of the viscus, which was 

 first described by M. Otto, as occurring in Semn. leucoprymnus, and 

 which was subsequently exhibited by Mr. Owen, at the Meeting of 

 June 1J, 1833*, as obtaining also in the only two species of the 

 genus which he had then examined, the Semn. Entellus, F. Cuv., 

 and the Semn.Jascicularis, Raffl., — a structure which he afterwards 

 described and figured in the 'Transactions' (vol. i. p. 65, pll. 9 and 

 10). Mr. Owen's impression that this remarkable modification of 

 the stomach is a generic peculiarity, receives confirmation from its 

 occurrence in the first previously unexamined species which has 

 been dissected within the Society's reach since the publication of 

 his remarks. 



An extensive series of Eulinice, chiefly from the collection of 

 Mr. Cuming, was exhibited, and an account by Mr. G. B. Sowerby 

 of the genus and of the characters of the several species was read, 

 part of which we now extract from the 'Proceedings.' 



Genus Eulima, Risso. 



Testa turrita, acuminata, polita, anfractibus plurimis ; apertura 

 ovata, postice acuminata ; labio externo subincrassato, varices ob- 

 soletos frequentes, subsecundos, plerumque efformante : operculo 

 corneo, tenui, nucleo antico.
