these, and are inspiratory between their costal cartilages. Between 
the diaphragmatic and intermediate sets of ribs, and between their 
cartilages they are throughout expiratory. The levatores costarum 
draw the posterior portion of the lower ribs backwards. In the ass 
and the dog, the upper fasciculi of the serratus magnus are expira- 
tory, the lower inspiratory, and the intermediate neutral. In man, 
the greater part of the fasciculi of this muscle is expiratory. In the 
ass, the lower fibres of the serratus posticus inferior are inspiratory, 
and the upper fibres expiratory. In the dog and in man, all are 
throughout expiratory.

Notice of a Black Lizard taken in Cheshire. By W. Wz ts, Esq. 
To Sir W. Jardine. 
Rimrose House, Bootle, Liverpool, April 12th, 1846. 
Sir,— When botanizing at Bidston, Cheshire, a few days ago, I 
met with a lizard adescription of which I send you, hoping you will 
excuse the liberty which I have taken and the imperfections of my 
remarks, as I am but a tyro in this department of science. 
The head, back and throat are a shining black ; scales of the belly 
and tail black, tipped with dark brown. The scales of the head are 
less numerous than in Zootoca vivipara, which it resembles in size 
and shape except that it is more slender, the tail is longer and more 
tapering, the head is more bulky, the eyes are perfectly circular and 
surrounded by a beautiful ring of minute scales, the scales forming 
the eyebrows do not project over the eye, and those of the back are 
much smaller than in the common species, which was abundant in 
the same locality.

I am aware that in the ‘ Mag. Nat. Hist.’ vol. i. p. 189, New Series, 
mention is made of a black lizard by G. W. in a note to his paper 
on Vipers, but I conceive that the difference between that and the 
one I have attempted to describe entitles me to consider them dif- 
ferent. I have kept a considerable number both of the viviparous 
and the sand lizard, but none of them evinced the very irritable, un- 
tameable disposition of this one; they are in general easily tamed, 
but the black one seizes everything that is put near it, and never
