extremities of the lateral nerves, and that it is the analogue of the 

 stomato-gastric of other Annelides, from which it differs only in its 

 origin. This, moreover, is not without precedent in science. M. de 

 Quatrefages, in his investigations of the Annelides, has shown that in 

 Eunice sangninea, for example, the visceral nervous system furnishes 

 the nerves both of animal and vegetative life." — Comptes Rendus,

On Ptychochcerus plicifrons (Centuriosus pleiceps, Gray). 

 By Dr. L. J. Fitzinger. 



The recorded species of the family Setigera, according to Dr. 

 Fitzinger, are nineteen in number, and form seven distinct genera, 

 namelv, Sus with nine, Potamochcerus with two, Porcula with two, 

 Ptychochcerus with one, Phacochcerus with two, and Dicotyles with 

 two species. 



Dr. Fitzinger proposes the name of Ptychochcerus plicifrons for 

 the Pig described by Dr. Gray under the name of Centuriosus plei- 

 ceps, and gives the following as the characters of the genus : — 



" Fore and hind feet with four toes ; skin wrinkled, divided on the 

 body by deep regular folds into three belts, and very sparingly 

 clothed with scattered bristles. Snout elongated into a short, move- 

 able, very broad trunk, truncated in front, which projects beyond 

 the lower lip. Ears very large and broad, rounded, flattened, and 

 hanging down loosely at the sides of the head. Tail not very short, 

 terminating in a tuft. Incisors, canines, and molars present in both 

 jaws; molars simple. No lobes of skin or wart-like elevations on 

 the cheeks. Upper canines not penetrating the snout. No secretory 

 glands at the posterior part of the back. Teats situated on the belly 

 and groin. Stomach simple. 



" Dental formula as in the genus Sus : g • — • ^— z = 44." 

 This Pig has only been discovered about three years, and is only 

 known in the domesticated state. It has been imperfectly noticed 

 by Bartlett and Gray. Dr. Fitzinger describes it from living speci- 

 mens in the Zoological Garden at Vienna. He also rejects the pre- 

 vious supposititious statements of the native country of this remark- 

 able form of Pig, which is said to be China or Japan, his reason for 

 so doing being that no travellers in those countries have ever men- 

 tioned its occurrence there, nor does its portrait appear among the 

 numerous figures of animals that we possess drawn by Chinese and 

 Japanese artists. Dr. Fitzinger thinks it probable that Abyssinia is 

 the native country of the species ; and in support of his view he quotes 

 a short notice by Dr. Theodor von Heuglin of a similar form, called 

 " Hassama " by the Abyssinians, which occurs wild among the 

 mountains of Simehn. Heuglin's note is as follows: — "This spe- 

 cies is somewhat smaller than our European Wild Swine, strongly 

 covered with bristles, dark blackish brown, spotted with greyish 

 yellow ; the head is short and obtuse ; the ears are very long and 

 pendent, and the litter always small. — Sitzungsb. der Akad. der
