of the cloacal aperture. Its interior was lined with hair opposite 
the vestibule of the pouch, but throughout the anteriorly directed 
fundus hairs were very sparsely distributed. 
The fundus possessed slight lateral recesses, within which the 
sparse hairs were larger. The position and appearance of the 
mammae on the dorsal wall of the pouch opposite the entrances to 
the lateral recesses corresponded accurately with those recorded 
in Dr. Stirling’s later paper in the Transactions of this Society of 
date October 6th, 1891.* 
In view of the numerous rather anomalous features in the 
organisation of Motoryctes, and the doubts which have occasion- 
ally been expressed as to its exact systematic position and affini- 
ties, I have thought it advisable while recording the arrangements 
of its muscles to aim at providing for a morphological comparison 
between these muscles and those of other forms. This I have 
striven to do largely by citation from the abundant records of 
mammalian myology, supplemented in certain cases, more par- 
ticularly in Monotremes and some Marsupials, by the results of 
my own examinations. Naturally, the records of the compara- 
tive myology of the Marsupialia have demanded the most careful 
scrutiny. The other orders to whose myology I have devoted 
some attention are the Monotremata, Edentata, Insectivora, 
Rodentia, and Carnivora. 
I must, however, disclaim any idea of making an attempt at 
giving anything like a complete acconnt of the muscular 
morphology, either of these orders themselves or of individual 
members of them. With this important reservation, the notes 
may yet serve a useful purpose in illustrating the comparative 
anatomy of the muscles of Votoryctes, especially as I have paid 
more particular attention to those types in the various orders 
(a) whose functional organisation is presumably not widely dis- 
similar from that of Wotoryctes—e.g., Talpa ewropea—(b) which 
offer certain remarkable points of structural resemblance—e.g., 
Chlamydophorus. 
I greatly regret that I have had no opportunity of dissecting a 
specimen of that interestiug insectivore the Cape Golden Mole 
(Chrysochloris), which would come under both of the above 
categories. My knowledge of the muscular anatomy of this 
animal has accordingly been derived from Leche’s notes in 
Bronn’s ‘“ Klassen und Ordnungen” (Sechster Band Abt. V.), 
which appear to have been derived from Dobson’s “ Monograph 
of the Insectivora,” Pts. I. and II., to which I have been unable 
to refer.
