A faint line also projects along the centre of the two first 

 segments of body, on the abdominal surface ; this surface 

 has two lateral free projecting membranes or plates, which 

 rise at the third ring of body, and run along its whole length 

 on each side, and between them, in this specimen, are 

 numerous distinct and naked ova. 



Pectoral fins short and broad, about A of an inch in 

 length by of an inch in breadth at base ; of 19 fin rays. 



Dorsal fin long and low; number of fin rays indistinct 

 and uncertain. 



Anal very small, apparently of 3 or 4 rays ; indistinct, 

 situated at termination of projecting lateral membranes. 



Caudal fin of an inch in length, with 5 or 6 rays. 



The colour of the fish, which has apparently been first dried, 

 and then put into spirits, is bronze or golden brown, espe- 

 cially brilliant on the snout or operculum. 



Length of body from point of snout, 2%% inches. 



Length of tail, 1 if inch. 



Total length of fish, 4a 6 o- inches. 



Length of head, of an inch. 



Length of snout in front of orbit, rather less than ^£ of 

 an inch. 



Length from front of orbit to back part of operculum, 

 rather more than of an inch. 



The fish was believed to have been taken in the lower 

 part of the Old Calabar Eiver, Western Africa .* 



(2.) Notes of two Specimens of the Chameleo cristatus (Stuch), the 

 Fringed or Crested Chameleon, from Old Calabar. By John Alex. 

 Smith, M.D. (Specimens exhibited.) 



This species was easily distinguished from all other chame- 

 leons by the presence of a large, erect, fin-like crest, sup- 

 ported by bony rays, which ran along its back and the base 

 of its tail. It was first discovered at the Gaboon in 1834, 

 and had since been observed at Fernando Po, and latterly 

 at Old Calabar. 



The general colour of the specimens, preserved in spirits, 

 is brownish or greyish brown above, with darker and lighter 



* Dr Smith has since placed the specimen, for determination, in the hands 

 of Dr Giinther of the British Museum, our first authority in Ichthyology.
