Scale 500 mm. Comparison with other species Microgale dry as (HB 105-114, GCL 30-32) is intermediate in size between Microgale thomasi (HB < 98, GCL ) and M. gracilis (HB , GCL ), and M. dobsoni (HB 29) and M. talazaci (HB > 115, GCL > 34). It is considerably larger than the other known species of Micro- gale (HB < 83, GCL < 25), see MacPhee (1987, table 2). It is readily disti

Scale 500 mm. Comparison with other species Microgale dry as (HB 105-114, GCL 30-32) is intermediate in size between Microgale thomasi (HB < 98, GCL ) and M. gracilis (HB , GCL ), and M. dobsoni (HB 29) and M. talazaci (HB > 115, GCL > 34). It is considerably larger than the other known species of Micro- gale (HB < 83, GCL < 25), see MacPhee (1987, table 2). It is readily distinguished from M. talazaci and M. dobsoni in which I2 is larger than the lower canine, while, as in the other species of Microgale, I2 is smaller or subequal to the lower canine. M. dryas is distinguished from all other species by the dorsal pelage, in which the guard hairs are flattened and broadened in their mid region. On cranial and dental charac- ters it is clearly associated with the cowani cluster [see MacPhee (1987), ], which includes M. cowani Thomas, 1882, M. parvula Grandidier, 1934, M. pulla Jenkins, 1988 and M. thomasi, and the gracilis cluster (M. gracilis). All members of the cowani and gracilis clusters have gracile skulls with a long, narrow rostrum and diastemata between the anterior teeth. The skull of M. dryas is larger than any of the other members of the cowani or gracilis clusters and is intermediate in elongation of the rostrum between M. tho- masi and M. gracilis. M. gracilis shows the greatest degree of attenuation of the rostrum, which is slender, with very long diastemata between the anterior teeth, in M. dryas the diastemata are moderately long (especially between the upper canine and P2) and the rostrum is narrow (in these dimensions the new species resembles M. cowani) but in M. thomasi the diastemata are small and the rostrum is relatively broader and shorter (see Table 1). The interorbital region of M. dryas is narrow and slightly concave in d
