males are available for examination they would prove to be larger than 

 the type is thus not confirmed by the present material. 



The hind feet in the type of A. langi show no vestige of a hallux. 

 The slight taxonomic significance of its presence or absence in this genus 

 is well indicated by the series of 6 young specimens of which the type of 

 langi is the mother of 5. Of the 6 young ones 3 have a vestigial hallux and 

 the other 3 are without it. It is also much more developed in one of the 

 three in which it is present than in the other two. It is also present in one 

 of the 3 young sotikx specimens (No. 181441 Nat. Mus.), and absent in 

 the other two and in 12 adults of the hindei-sotikse series. 



SORICIDiE 



As stated above (p. 2), the shrews of the Congo Expedition were 

 early assigned to Mr. Hollister, of the United States National Museum, 

 for determination, and his report on them was published in this Bulletin 

 in October, 1916. 1 The following statement in respect to the extent and 

 character of the collection is made in the introduction to his paper: 



The shrews collected by Herbert Lang and James P. Chapin on the American 

 Museum Congo Expedition number 183 specimens, of 15 species and 3 genera. 

 Almost one half of the species are new. This is not altogether surprising when it 

 is considered how few shrews have been described from the Congo as compared 

 with other parts of Africa. It nevertheless seems remarkable that five of these new 

 species should be members of the small group of 'naked-tailed " Crociduraoi which 

 only about ten forms were heretofore known. Five forms of Crocidura which have 

 been recorded from the general region are not represented in this collection. These 

 are Crocidura turba turba Dollman, C. t. tarella Dollman, C. poensis attila Dollman, 

 C. boydi Dollman, and C. nigrofusca Matschie. Races of C. hildegardese and C. 

 fumosa, as well as representatives of several west coast species also might reasonably 

 be expected. 



In order to complete the record of the Congo collection of insecti- 

 vores, the shrews obtained are here listed, as determined by Mr. Hol- 

 lister.
