Miller — Seven Neio Hats collected in Siam. 149 



Teeth. — The teeth are relatively broader than in Mas jerd'ini, l)ul in 

 structure they show no peculiarities. 



Mai.suremeiits. — P]xternal measurements of type: total len<ith, 400; head 

 and body. 1!)7: tail. 20:>: hind foot, .'J8 (3(5): ear from meatus, 21.5; ear 

 from crown, IS; width of ear. lo. Ten specimens (five of each sex) from 

 the type locality a\erage: total length, 372 (35(3-400): head and body, 187 

 (l;)2-l()7): tail vertebra, 185.5 (175-203); hind foot, 38.(> (3(i-40): hind foot 

 without claws, 35.8 (34-39). 



Cranial measurments of type: greatest length 4(> (30.())*; basal length, 

 40 (30); basilar length, 37 (27.(5); palatal length, 19 (14.8); least width of 

 palate between anterior molars, 4.(5 (3.8); diastema, 13.4 (9.4); length of 

 incisive foramen, 7.4 ((5.(5); combined breadth of incisive foramina, 4 (3); 

 length of nasals, 18.(5 (14); combined breadth of nasals, 5 (3.6); zygomatic 

 breadth, 19.8 (15.4); interorbital breadth. 7.(5 ((5): mastoid breadth. 15 

 (13); breadth of braincase above roots of zygomata, 1(5 (15); depth of 

 braincase at front of basioccipital, 12 (10.4); frontopalatal depth at pos- 

 terior extremity of nasals, 9 (8); least depth of rostrum immediately be- 

 hind incisors, 8 ((5.8): maxillary toothrow (alveoli), 7 ((i): width of front 

 upper molar, 2 (1.(5): mandible. 24.(5 (18.0): mandibular molar series 

 (alveoli), 7 (5.8). 



Spenme/i-s c.ravn'ucd. — Twenty-one, all from the type locality. 



Jteinarkx. — Mu^ Kurifer is somewhat closely related to ^f^^s jerdoni, 

 though immediately distinguishable by its much greater size. Two 

 adult specimens of the latter measure: total length, 325 and 322; head 

 and body, 200 and 192: tail vertebrte, 125 and K'.O: hind foot, 31.5 (30.5) 

 and 30.5 (29.5); ear from meatus, 19 and 19; ear from crown, 1(5 and 16; 

 width of ear, 14 and 13. Externally >¥m.v .*«/■//>?' is probably mvich like 

 the 15ornean Mux rajah Thomas; but the skull is considerably smaller. 

 Some of the cranial measurements of the type of Mux rajah are: greatest 

 length, 51; basilar length, 41; zygomatic breadth, 22; nasals, 19; dias- 

 tema 14.5 



*Measurements in parenthesis are those of an adult specimen of Mus 

 jerdoni from Mount Mooleyil, Hurinah.
