" In proportion to the size of the body the head of Cham. Bibroni 

 is short, and particularly the muzzle, which is very acute at the apex. 

 Viewed from above the helmet it would present an elongated oval, 

 rounded behind and acute anteriorly, were it not for its contraction 

 between the eyes, which is not the case in Ch. Senegalensis. The 

 accessory lobes at its posterior part are very small, and might easily 

 be overlooked. Perhaps, however, they may be larger in the male, 

 (for the present individual, it is to be observed, is a female,) but of 

 this I have no means of judging. The length and slenderness of 

 the tail are remarkable. The granulations of the body are small 

 and even. The general colour is purplish black, passing on the 

 sides of the belly, on the loins, and posterior limbs, into olive-green ; 

 the inside of the limbs, and the median line of the abdomen, are pale 

 reddish-yellow."

The first meeting of the Session took place on Saturday, Dec. 15, 

 1838, Dr. Greville, V.P. in the Chair. 



The first communication read was upon " The Geology of the 

 neighbourhood of Kelso, by C. Le Hunte, Esq." There was next 

 read a paper by Sir John Graham Daly ell " On a singular mode of 

 Propagation among the Lower Animals," by which last phrase the 

 Zoophyte group is to be understood. The communication was ac- 

 companied by beautiful and delicate engravings, preparing for a 

 splendid work on the Zoophytes with which Sir John has for years 

 been engaged. The following modes of propagation among differ- 

 ent members of the group were referred to, — by means of ova; 

 through the medium of an animal discharged from an external cyst 

 of the parent, which, after enjoying active motion for a time, be- 

 comes stationary, is metamorphosed, and thus attains its perfect 

 state. It was likewise remarked, that from the Hydra tuba, which 

 is a Hydra proper, prominences bud externally, which are at first 

 shapeless, and on being detached become perfect animals ; and also, 

 that an animated moving corpuscule, which may, as such, be arti- 

 ficially liberated from Actinia, will become a perfect foetus if retained,
