INSECTIVORA 



zygomatic arch or postorbital process, and the tympanic annulated 

 and not forming a bulla. Upper molars tritubercular, the cusps 

 being arranged in a V. Pubic symphysis short ; tibia and fibula 

 distinct. Vertebrae : C 7, D 15, L 4, S 5, C 23. No caecum. The 

 penis is carried forwards and suspended from the abdomen ; the 

 testes are received into perineal pouches ; the mammary glands are 

 post-inguinal ; the uterine cornua end in caecal sacs. 



Solenodon. 1 Dentition : i f , c -f , p f , m -f ; total 40. This genus, 

 with S. paradoxus and S. cubanus (Fig. 293), from Hayti and Cuba 



Fio. 293. Solenodon cubanus. x '. (From Peters, Abh. Akad. Berlin.) 



respectively, alone represents the family. These species, which 

 differ chiefly in the colour and quality of the fur, have a remark- 

 ably long cylindrical snout, a long naked tail, feet formed for 

 running, and the body clothed with long, coarse fur. 



The position of the mammas quite behind on the buttocks is 

 unique among Insectivora. The first upper incisor is much enlarged, 

 and this and the other incisors, canines, and premolars, closely 

 resemble those of Myogale ; the second lower incisor is, as in 

 Potamogale, much larger than the anterior one, and is deeply 

 hollowed out internally. While thus apparently showing relation- 

 ship with the Talpidce, the form of the crowns of the molar teeth 

 connects them with the next family.
