Measurements :—Head and body 96 millim. ; tail 74; hind 
foot 18°4; ear 14; end hairs of tail 20. 
In a male specimen the head and body measure 103, 
tail 84. 
Skull: greatest length 30 millim.; greatest breadth 16°5 ; 
breadth of brain-case 14; constriction 4°6; nasals 11:7 x4; 
interparietal bone 4x 9°9; height above auditory bulle 12; 
height at front of palate 5°1; basal length 26; henselion to 
back of palate 9°3; back of palate to foramen mag. 14; 
palatal foramina 3°5 x 2°6; diastema 6°6; molar series 3°6 ; 
outside ™s:! 6:2, inside4. Mandible (bone only), length 15°2, 
height at coronoid 8°3. 
The most noticeable character in the skull which distin- 
guishes this animal from its ally G. murinus is its greater 
height and more rounded shape; the skull is deeper in pro- 
portion, through the brain-case and auditory bulle, than any 
Graphiurus yet described; the teeth also differ in pattern. 
I have selected a specimen received from the Lisbon 
Museum on a former occasion as the type of this species. The 
present collection contains two specimens from Galanga; one 
of these is very interesting, its tail being in the peculiar 
state which led Dr. Jentink into proposing the genus 
Clarviglis. ‘This disease seems to be rather common in the 
African dormice. ‘The bones of the tail coalesce distally and 
waste away, the tail gradually getting shorter; about six or 
more vertebre are affected at the same time, forming a single 
bone tapering to a point, the muscles also wasting away. 
One specimen in the Museum has only a length of 5 millim. 
of healthy tail left at the base; in another the tail is normal 
for about 20 millim. ‘The skin thickens in converse propor- 
tion to the wasting of the bone, so that the tail becomes 
club-shaped; and the shorter the tail becomes the broader is 
the end of the club. The disease does not affect the growth 
of the hair, for in one specimen the hairs are 27 millim. in 
length. ‘lhe animals seem well nourished and otherwise 
healthy.
