Fig. 2 Dorsal view of skins from left to right of Microgale drouhardi 

 (FMNH 154565), M.fotsifotsy (FMNH 154590) and M. parvula 

 (FMNH 151620). 



incisors (dll anddil) respectively considerably smaller than II and 

 il (see Figs 4 and 5). Principal cusp of dll slender, distostyle 

 present, no anterior accessory cusp; morphology of deciduous sec- 

 ond upper incisor (dI2) similar to 12 but smaller; deciduous third 

 upper incisor (dI3) very small, less than height of distostyle of dI2. 

 Deciduous upper canine (dC) subequal in height to deciduous 

 second upper premolar (dP3), distostyle distinct, anterior accessory 

 cusp present. Trace of anterior cuspid on deciduous first upper 

 premolar (dP2); deciduous second upper premolar (dP3) with dis- 

 tinct mesostyle and distostyle present. Deciduous first lower incisor 

 (di 1 ) subequal in height to second deciduous lower incisor (di2) but 

 considerably smaller in occlusal area; di2 similar in morphology to 

 i2, with or without a small lingual cusp. Deciduous third incisor 

 (di3) shed in all specimens examined. Deciduous lower canine (dc) 

 and first lower premolar (dp2) similar in morphology to respective 

 permanent counterparts but smaller, with trace of anterolingual 

 cuspid; deciduous second lower premolar (dp3) taller than dc (un- 

 like permanent dentition), metaconid present or indicated. 



Eruption sequence partially determined: i3 to 13, II to il, P2/p2, 

 I2/i2, P4/p4; P3/p3 and C/c last teeth to erupt but sequence remains 

 to be determined. 



Intraspecific variation. The known populations of this 

 undescribed species are geographically widely separated and this is 

 reflected in the moderately high degree of intraspecific variation. 

 There is slight variation in pelage coloration: specimens from PN de 

 la Montagne d'Ambre are generally paler than those from RS 

 d'Ambatovaky, RNI de Zahamena and RNI d'Andringitra which 

 also often have a reddish buff wash; specimens from RNI de 

 Zahamena often show a reddish buff wash ventrally, while those 

 from RNI d'Andringitra have a buff wash. Specimens from the RNI 

 d'Andringitra and RNI de Zahamena populations are larger on 

 average than either of the other populations (see Table 1 ), particu- 

 larly in cranial dimensions. The two specimens from Marosohy, 

 although geographically closer to the RNI d'Andringitra specimens 

 in southeastern Madagascar are, however more similar to the PN de 

 la Montagne d'Ambre specimens in size, as is the single juvenile 

 specimen from RS d'Ambatovaky. There is some evidence of corre- 

 lation between size and altitude; specimens from localities at lower
