254 MR. ST. GEORGE MIVART ON [Apr. 22, 
37. TINNUNCULUS SPARVERIUS (Linn.). 
A single male, from the plain of Valencia, has the body below 
wholly without spots, as the bird described by Swainson as Falco 
isabellinus (An. in Men. p. 281). See v. Pelzeln’s remarks on this 
supposed local race in his List of Falconide in the Imperial Col- 
lection (Verh. zool.-bot. Ges. 1863, p. 627). 
41. MicrasTUR ZONOTHORAX. 
Climacocereus zonothoraz, Cab. Journ. f, O. 1865, p. 406. 
A single skin, immature, but no doubt referable to this northern 
form of M. rujficollis sive xanthothorax as described by Cabanis. 
Whether it is really distinct we have not yet sufficient materials to 
give a decided opinion. 
47. CRYPTURUS STRIGULOSUS. 
Tinamus strigulosus, Temm. Pig. et Gall. ni. p. 594. 
Mr. Goering’s skin agrees generally with the specimens in the 
British Museum thus marked (cf. Gray, List of Gall. p. 100), but 
has the middle of the throat pure white. 
3. Notes on the Myology of Menopoma alleghaniense. By 
Sr. Gzorce Mivart, F.L.S., Lecturer on Comparative 
Anatomy at St. Mary’s Hospital. 
Having been engaged for some months in working at the Urodele 
Batrachians, the liberality of the authorities of the Royal College of 
Surgeons, and the kindness of my friend Mr. W. H. Flower, have 
placed at my disposal certain specimens well preserved in spirit of 
wine. One of these is the subject of the following notes. 
In describing the muscles I think it better to give each a distinct 
name. In doing so, however, I by no means intend to imply that 
there is necessarily a real relation of homology between the several 
muscles of Menopoma and those of Mammals and Sauropsidans. It 
may well be that in many cases the resemblance is merely one of 
analogy, resulting from similarity of conditions. 
The general form of this species is well known, with its broad and 
flat body, its very wide and flat head, and rounded muzzle. The tail 
has a rather deep cutaneous fin both above and below ; but while it is 
continued along the whole length of the dorsum of the tail, it only 
extends along about the hindmost sixth of its inferior border. 
The skin is nearly smooth all over, and is destitute of any tubercles 
or prominences. It is smoothest on the middle of the crown of the 
head and on the middle of the belly. Numerous short transverse 
wrinkles, however, extend, at short intervals, across the throat and 
along the whole back and belly ; on the tail, on account of the great 
lateral compression of that organ, these wrinkles assume a vertical 
direction.
