Arr ingenienl of the small Tenrecidss. 303 



a*. Skull heavily built. Lnterorbital region 

 parallel-sided. A high lambdoid 

 creel present. Zygomatic process of 

 squamosal prominent, projecting late- 

 rally beyond brain-case, reeth stout 

 and heavy; posterior secondary cusps 



reduced or absent 1. Nesogale, g. n. 



b 2 . Skull papery ; tapering forwards evenly 

 from the brain-case. Lambdoid crest 

 not or scarcely developed, and nut 

 interrupting the smooth even profile 

 of the skull. Zygomatic process of 

 squamosal minute, surpassed by the 

 lateral inflation of the brain-case. 

 Teeth Light and delicate; posterior 

 secondary cusps well developed .... 2. Microgale, Thos. 

 b. Internal basal lobe of molars obsolete. 

 Incisors subequal, the bicuspid canine 

 little surpassing /'. Muzzle long and 

 slender, the teeth widely spaced. Fore 



claws longer than hind 3. Leptogale, g. n. 



B. Claws markedly fossorial, the third anterior 

 twice the length of the third posterior. 

 Canines dominant, always surpassing the 

 anterior incisor ; their secondary cusp 

 quite small. 



a. Pollex absent. Fur ordinary. Skull less 



broadened behind 4. Xesorgctes, g. n. 



b. Pollex present. Pur velvety, mole-like. 



Skull more broadened behind 5. Orgzorictes, Grand.

A larger heavier form, related to Microgale, but with 

 more powerful teeth and heavily ridged, skull. In side view 

 the skull is peculiar for the sinuosity of its profile, the hi°-h 

 transverse occipital ridge being succeeded anteriorly by a 

 concavity, in front of which again there is a marked con- 

 vexity whence the profile runs straight to the tip of the 

 nasals, or is even slightly concave or sinuous. Below there 

 is a marked ridge connecting the postglenoid processes with 

 the entopterygoids, the ectopterygoids being practically 

 obsolete. 



Teeth essentially like those of Microgale, but stouter and
