MAMMALIA.

Phascogale. Prof. ScUegel has received from the Am Islands two species, 
which he describes (1. c.), viz. Ph. wallacei (Gray), p. 355, and Ph. longicau- 
data, sp. n., p. 356. 
Phascogalea thorhecldana, sp. n., Schlegel, Nederl. Tydschr. Dierk. iii. 
' 1860, p. 257, from the island of Salawattie. 
Piddpliys. Dr. Engelmann has made some remarks on the young 
(twelve in number) found attached to the teats of an Opossum j they may 
have been eight or ten days old ; the body measured 9 lines, the crooked tail 
3 lines ; the weight was 21 or 23 grains. Trans. Ac. Sc. St. Louis, ii. 1866, 
p. 224. 
>\Didclphys crassicaudata. Prof. Giebel describes the skull, 1. c. p. 396. 
MONOTREMATA. 
Ornithorhynchus. Prof. Gegenbaur denies that the structure of, its heart 
indicates a transition of the heart of Mammalia to that of Birds. Jena 
Zeitschr. Medic, ii. pp. 375-383. 
A.PcIndna hystrix. Mr. St. G. Mivart has examined its myology, Trans. 
Linn. Soc. xxv. 1866, pp. 379-403, tab. 52, 53. In the concluding chapter 
he shows that these researches throw additional light on the serial homology 
of the limbs, especially that, if the radial (greater) tuberosit}’^ be considered 
to be the homotype of the tibial (smaller) trochanter, and the ulnar (lesser) 
tuberosity that of the peroneal (greater) trochanter, the mm. supra- and 
infraspinatus with the teres major may be expected to coiTespond with the 
iliacus and j^soas, and the suhscapidaris and teres major with the glutcei. He 
linally considers the bearing of these muscular relations on the question as 
to what parts of the ilium answer to the several parts of the scapula.
