Ateles Frontalis, a new species of Spider-Monkey. — At a late meeting of 

 the Zoological Society, Mr Bennett gave this name to a species, which he 

 considers to be new, and an individual of which is at present living in the 

 Society's garden. Its character is thus given, — At. atery macula frontali 

 semilunari alba, statura At. atri, F. Cuv. 



By the white patch on the forehead, and the radiation of the hair from 

 the back of the neck, this monkey approaches the At. hybridus, described in 

 the Dictionnaire Classique d'Histoire Naturelle, by M. Isidore Geoffroy St 

 Hilaire. In the latter, however, the colours of the body are varied, and 

 generally light, the darkest tint which is mentioned as occurring on the 

 spacimen described, being the pure brown of the head, and anterior limbs. 

 In the Society's individual, on the contrary, the whole of the hairs, with the 

 exception of the frontal patch, are jet black ; the naked parts of the skin 

 are also black, except a flesh-coloured space on the face, including the 

 eyes, nose, and lips. It has been suspected, that as the lighter coloured 

 species of Ateles advance in age, they acquire the black which is so generally 

 prevalent in the group ; but this change of colour yet remains to be proved.

Mongrels between a Dog and a She Wolf. — Dr A. F. Wiegmann, jun. 

 relates the following circumstance as occurring at the Isle of Peacocks, near 

 Potsdam. A setter dog copulated with a she wolf; and she afterwards gave 

 birth to three female pups, differing very much from each other. One, 

 which died, resembled a wolf more than the two others, particularly in the 

 hair, having, on the anterior parts of the legs, the black line which charac- 

 terizes that animal. The second also resembled the mother, excepting in 

 the position of the eyes, which was the same as in the dog. The third was, 

 properly speaking, a setter dog, but imperfect in some respects ; its character 

 was gentle, whilst the others had a ferocious appearance. The father was 

 white, with brown spots ; of the little ones, on the contrary, the first had 

 the hair and colour of the wolf; the second was white on the throat, cheeks, 

 and on the sides of the neck, and black on the back ; and the third had a 

 white band on the fore part of the neck, and between the legs, the back of 

 the same colour as the second, and the ears rounded, pendent, and of 

 moderate length. The tail was not erected in any of the three — Isis. 



^Observations on the Hyacinthine Maccaw. By E. T. Bennett, Esq,.--* 

 Tbe Hyacintine maccaw was first described, in 1790, by Dr Latham, in 

 his Index Ornithologicus, under the name of Psittacus hyacinthinus, from 

 a specimen in Parkinson's, otherwise the Leverian, Museum. In the 

 Museum Leverianum, under the date of 1792, and afterwards in his Zoological 

 Miscellany, Dr Shaw described and figured it as the Psittacus augustus, 

 quoting Dr Latham's synonyme, and preserving it in the English name. 

 Subsequently, the bird was fully characterized, with an interesting account 

 of its habits, under the name of Guacamayo azul, by another observer of 

 the close of the last century, M. d' Azara ; in the French translation of 

 whose work, M. Sonnini added a note, pointing out the resemblance 

 between D'Azara's bird and that of Dr Latham. In the second edition 

 of the Nouveau Dictionnaire d'Historie Naturelle, M. Vieillot considered the 

 former as a distinct species, and named it Macrocercus glaucus ; but, in his 

 Galerie des Oiseaux, he corrected tMs error, and united tJie.tv^o birds under
