452 THE ANATOMY OF VERTEBEATED ANIMALS. 



tinated lower incisor teeth are found in tlie Clieiropteran 

 genera, Diphylla and Desmoclus. 



But Galeopithecus differs from the Bats completely in 

 the structure of the fore limbs ; in the position of the hind 

 limbs and the absence of a calcar ; in the two-fanged outer 

 incisors and canines ; and in the presence of a ccBcum. 



On the other hand, the peculiarities of the skull and 

 brain are mainly insectivorous, as is the two-fanged canine ; 

 and I see no reason for dissenting from Prof. Peters' view 

 that Galeopithecus belongs neither to the Primates, nor to 

 the Cheiroptera, but that it is an aberrant Insectivore. 



With respect to other Insectivora, it is worthy of note, 

 that Macroscelides has the radius and the ulna ankylosed. 

 The Tupay<B possess a large coecum. Chrysochloris has 

 pectoral mammary glands ; Centetes and the Moles have the 

 penis pendent. 



The Tupayce are soft-fuiTed, long-tailed, tree-loving 

 animals, with complete bony oi'bits and a large coecum, 

 and are those Insectivora which most nearly approach the 

 Lemurs. 



The Shrews (Sorices) most nearly resemble Rodents out- 

 wardly, being very like small mice. The zygoma is 

 imperfect, the tibia and fibula are ankylosed, and the pubic 

 bones do not meet in the symphysis. There are sixteen to 

 twenty teeth in the upper jaw and twelve in the mandible. 

 Canines are absent, and there are sis incisors above and 

 four below. The inner lower incisors are greatly elongated 

 and proclivous, and some of the teeth not unfrequently 

 become ankylosed with the jaws. There is no ccecum, and 

 peculiar musk glands are sometimes developed at the sides 

 of the body. 



The Moles (Talpinoe) have no external ears, and the eyes 

 are rudimentary. The fore limbs are much larger than the 

 hind, and are inclosed within the integument up to the 

 carpus. The palmar surface of the broad manus is turned 

 outwards and backwards. 



The manubrium of the sternum is very broad, and its ven- 

 tral surface gives rise to a strong median crest. The scapula
