that it is the same as a small Lemuroid in spirits that we have 

 lately purchased, labelled "La plus petite Macque de Madagascar 

 entre Manham et Teneriffe." 



It agrees with Buffon's figure in all particulars, especially in the 

 acuteness and prominence of the nose beyond the lips. As the animal 

 has only been described from a stuffed specimen, I may add : — The 

 muzzle naked, having a central longitudinal groove on the underside 

 to the border of the lip ; the whiskers are long ; the ears are rather 

 large, about half the length of the head from their front edge, 

 rather naked, with short close hairs on the outer surface. The hind 

 legs and feet are strong. 



The head is 1 1 inch long, the body 3| inches. The tail is cylin- 

 drical, "S- inches long, covered with close hair, and with scattered, 

 longer, soft hair near the end. The hind leg is 1| inch long, and 

 the hind foot Ig inch long, when the animal is measured taken out 

 of spirit. 



The examination of the skeleton has proved this animal to be the 

 Azema Smitliii ; and, like this, it has the nose and the intermaxillaiy 

 bones produced not so much as in the Galago Demidoffii. This 

 prominence of the intermaxillaries at once distinguishes it from 

 MurUemur miirinus, which is otherwise very like it and comes from 

 Madagascar, the skull of which is also at once known by the existence 

 of a large round perforation on each side of the hinder edge of the 

 palate, weU figured by Mr. Mivart, and not found in the skuUof either 

 Azema Smithii or Galago Bemidqffli. 



Note on the Anatomy of Comatula rosacea. By E. Pereier. 



Last summer, at the laboratory of experimental zoology of M. 

 Lacaze-Duthiers, at Eoscofi' (Finisterre), I endeavoured to clear up 

 the obscure points which still exist in the anatomy of the Comatidce, 

 the last remains of the rich fauna of Crinoids presented to us by 

 geological strata. Our Comatidce are provided with ten arms, ar- 

 ranged in pairs, and radiating round a disk, upon which is placed a 

 visceral sac containing the digestive apparatus. The arms are fur- 

 nished on each side with a row of alternate phimdes, each joint of 

 the arms bearing a pinnule upon one of its sides. The pinnules 

 seem to be a repetition on a small scale of the arms themselves, but 

 they do not bear secondary pinnules. 



On the disk we see two orifices — one central, which is the mouth ; 

 the other lateral, corresponding to the interval between two pairs 

 of arms, and situated at the extremity of a sort of fleshy chimney 

 terminated by eight lobes; this is the anus. Round the mouth 

 there is a vascular ring, which, opposite to the base of each pair of 

 arms, emits a vascular branch ; and this, bifurcating at the base of 

 each pair, furnishes each arm with a canal called the radial or ten- 

 tacular canal. The vascular ring in the intervals between the five 

 primary radial canals gives origin, on its inner margin, to eight or 

 ten contiguous digitiform tentacles, which are largest at the middle 

 of each interval, and become smaller in the neighbourhood of the
