2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 56 



Measurements. — Head and body, 170 mm.; tail, 26; hind foot/ 

 25. Skull : condylo-incisive length, 42 ; zygomatic breadth, 27 ; na- 

 sals, 15.5x2.3; interorbital constriction, 11.2; palatal length, 25; 

 breadth of palate, including first molar, 17; length of upper tooth- 

 row, 21.8;^ condylo-incisive length of mandible, 34.5. 



This species is closely allied to hindei of Kitui in coloration and 

 general proportions. It differs decisively in the greater length and 

 attenuation of the nasal bones, the lighter zygomatic arches, and 

 smaller skull. The type skull shows some asymetrical peculiarity. 

 On the right side the premaxillary and frontal processes join and 

 shut out the maxillary from the nasal, while on the left side these 

 two bones are separated by the maxillary which borders the nasal 

 for a length of 2 mm. There are four other specimens in the collec- 

 tion from the Sotik. These all agree with the type in the great 

 length and attenuation of the nasals. 



CROCIDURA SURUR^, new species 



Lado Giant Shrew 



Type from Rhino Camp, Lado Enclave ; adult male ; number 

 164637, U. S. Nat. Mus. ; collected by J. Alden Loring, January 18, 

 1910; original number, 8777. 



Characters. — Smaller than nyanscB, but proportions the same ; dor- 

 sal color lighter and grayer, without any brownish wash to the under 

 parts. 



Coloration. — Upper parts broccoli brown, merging gradually on 

 sides to grayish, showing everywhere a grizzled effect, due to the 

 grayish subterminal area of the hair showing through. Limbs whit- 

 ish. Under parts grayish with a faint buffy wash. Lateral glands 

 conspicuously marked by an oblong patch of short white hairs. 



Measurements. — Head and body, iii mm.; tail, 64; hind foot, 17. 

 Skull: condylo-incisive length, 28.5; breadth of brain-case, 12; length 

 of upper tooth-row, 13; condylo-incisive length of mandible, 18. 



There are in the collection a series of nine specimens from the 

 type locality. These are remarkably uniform in color and propor- 



'All measurements of the hind foot given in this paper exclude the 

 claws and were taken from the dried skins, which afford better means of 

 comparison than the collector's flesh measurements. 



*Some departure from the usual alveolar measurements of the tooth 

 row has been made, the measurement as given throughout the paper 

 being taken from the posterior end of the tooth row to the outside border 

 of the central incisor. In the smaller species this measurement can be 

 taken with greater preciseness than the alveolar length.
