52 EINAB LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 



The lateral musk-glands are strongly developed and emit even in the dried 

 state of the skin a quite strong odour of musk. 



Length of head and body of the dry specimen about 67 mm.; length of tail 

 84 mm.; length of hindfoot resp. 15 mm. without, 16 mm. with claws. 



Condylo-incisive length of skull 18,4 mm. The greatest breadth of the skull 

 cannot be ascertained because it is partly broken on the right side behind, but it is 

 probably about 8 mm. Interorbital width 4,3 mm., palate length to gnathion 7,5 

 mm., length of maxillary series of teeth 8 mm. 



The anterior incisors have the posterior cusp pointed but not very high, not 

 reaching half the height of the anterior margin of the succeeding tooth. First uni- 

 cuspid rather large and sharply pointed. The second unicuspid does not reach half 

 the height of the first, and it is also a little lower than the third. The third overlaps 

 the second so that, if the teeth are seen from the coronal surface, the latter tooth 

 looks smaller than it really is. But if seen from the lateral side it shows its real 

 dimensions better and proves to be as well much higher as even broader than the 

 fourth. The latter is much the smallest in the series, and it does not reach more 

 than half the height of the third unicuspid. 



The relative size of the second and fourth unicuspids as described above forms 

 an important distinguishing characteristic from Sylvisorex sorella Thomas with which 

 this species, no doubt, is closely related. In S. sorella the second unicuspid evidently 

 is much smaller than in the present species as it is said* to be subequal with the 

 fourth, and both are only » about half the height » of the third, while in the present 

 species there is as much difference in height between the fourth and the second 

 unicuspid as between the second and the third. 



The last upper molar of S. sorella is said to be of » squarish form». In this 

 species it is more triangular than square in outline. 



The long-tailed Shrew from Liberia which Miller has named Myosorex muri- 

 cauda,^ but which Thomas placed in the genus Sylvisorex when creating this,^ differs 

 decidedly from the present species in having only 3 unicuspid teeth in the upper 

 jaw, and in having no » trace of scales or annulation* on the taif. The latter organ 

 is also shorter than in S. sorella and sorelloides.

A specimen of Giant Shrew was caught ^^i 1911 in the Meru country not 

 far outside the forests of north-eastern Kenia. The dimensions of this specimen are 

 as follows viz. head and body (dry specimen) 136 mm., tail 89 mm., and hind feet 

 about 23 mm. with claws, 21 without claws. These measurments agree rather
