638 INSECTIVORA 
Ericulus.i—Dentition: «2, ¢4, p 3,m; total 36. Vertebre: 
C7,D 17, L 6,8 4, C 9. The single species, £. setosus, is a 
Hedgehog-like animal, having the whole upper surface and the 
short tail densely covered with close-set spines. The facial bones 
are much shorter than in any of the preceding genera, and the 
first upper incisor is elongated, as in Erinaceus. Judging from 
the slight development of the cutaneous muscles compared with 
those of the true Hedgehogs, it is probable that complete involution 
of the body does not take place. 
Subfamily Oryzorietinze.—Tibia and fibula united ; testes near 
urethra ; fur without spines. 
Microgale.2—Dentition : 13, ¢4, p 3,m%; total 40. This genus

includes AL. longicaudata and AL. cowani, both of which are small 
Mouse-like species, the former with a tail double the length of the 
head and body, and having 43 caudal vertebre ; teeth like those of 
Centetes ecwudatus, but, owing to the comparatively much shorter 
muzzle, not separated by wide spaces, and the last premolar and 
molar with internal basal processes. 
Oryzorictes.-—Represented by two species, 0. hova and 0. tetra- 
dactylus, the latter distinguished by the presence of only four digits 
in the manus, the three inner having long laterally compressed 
fossorial claws. The general form of the head and body of the 
two species known is like that of a Mole. These animals burrow 
in the rice-fields and do much damage to the crops. 
Family CHRYSOCHLORID&, 
Skull conical, not constricted between the orbits, without post- 
orbital process, but with well-developed zygomatic arch and tympanic
