which rings of scales are visible ; on the apical portion of the tail the 

 hairs are longer, slightly exceeding one eighth of an inch in length ; 

 the hairs on the under side of the tail are of a deep buff colour, and 

 those of the upper side are black and yellow, excepting at the apex, 

 where all the hairs are black. 



The teeth in this species agree in number with those of Phascogale 

 penicillata, and in fact scarcely differ in any respect, making allow- 

 ance for the diiFerence in the size of the animals. The two front in- 

 cisors of both upper and lower jaws are perhaps smaller in propor- 

 tion, and the third false molar in the lower jaw is decidedly smaller 

 in proportion, being scarcely visible unless the gum be removed. 

 The last molar of the upper jaw is of the same narrow form, and placed 

 obliquely as in P. penicillata. 



Not having a skull oi P. penicillata, I am guided in my observations 

 by M. Temminck's figure in the ' Monographies de Mammalogie.' * 

 Upon comparing the skulls of P.flavipes with the same figure, the 

 resemblance is great ; in the smaller animal, however, the skull is 

 somewhat narrower in proportion (especially the fore part) ; the na- 

 sal bones are not so broad at their base. 



Phascogale murina, from North of Hunter's River, New South 

 Wales. 



This species may be readily distinguished from the former by its 

 much smaller size, being in fact rather less than the common mouse 

 {Mus musculus), or less than half the bulk of P.flavipes. The fur is 

 rather short and soft ; its general hue is gray with a faint yellowish 

 tint, the longer hairs on the upper parts of the body being gray at 

 the apex, and the shorter hairs tipped with pale yellow or cream 

 colour ; the feet and under parts are white, as are likewise the sides 

 of the face beneath the eye. All the hairs of the body are of a deep 

 slate colour at the base. The tail is covered with very minute closely 

 adpressed silvery white hairs. The dentition is evidently that of an 

 adult animal : the canines and anterior incisors of both upper and 

 lower jaws appear to be smaller in proportion than in P.flavipes. 



Mus Hayi, from Morocco. 



This species, which is rather larger than Mus musculus, was pre- 

 sented to the Zoological Society by E. W. A. Drummond Hay, Esq., 

 Corr. Mem., after whom I have taken the liberty of naming it. 



Mus Alleni, from Fernando Po. 



This species is less than the harvest mouse {Mus messorius), and 

 of a deeper colour than the common mouse {3Ius musculus), being 

 in fact almost black. The ears are smaller in proportion, and more 

 distinctly clothed with hairs. The tail is very sparingly furnished 

 with minute hairs. The tarsi are covered with blackish hairs above; 

 the toes are dirty white. 



I have named the species after Lieut. W. Allen, R.N., Corr. Mem. 

 by whom it was discovered and presented to the Zoological Society. 



* In M. Temminck's figure the three lateral incisors of the upper jaw are 

 represented as being close to the anterior pair. There is, however, a space 

 between the anterior incisors and the lateral, both in P. 'penicillata and in 

 the two species here described.
