MAMMALIA INSECTIVORA. 25 



midas (Hedenb.) is a new species from Scmiaar, described by 

 Sundevall (1. c. p. 207, tab. ii, fig. 7), with the diagnosis : " Supra uigro- 

 f'uscus, subtus grisescens ; membraua ad latera dorsi, ventre iiifimo artu- 

 busque nudis." Kotschy found the same species in Seunaar.

 by H. Rascli. (Nyt. Magaz. for Naturvidensk, iv, Heft. 1.) 



The Reporter has translated this description abridged, and accompanied it 

 with remarks, in the Archives for 1843, p. 261. 



Some interesting remarks on the distribution and migration of Vesperugt) 

 Nilssonii have been made by Blasius in his ' Travels in European Russia' 

 (p. 26-i). Gray has instituted (in the Ann. Nat. Hist, xi, p. 117) a Keri- 

 coula brasiliensis, "blackish, hairs with brownish tips, rather paler beneath; 

 ears large, pointed, curved backwards." 



INSECTIVORA. 



An excellent Monograph on the genus Sorex has been 

 published by Sundevall in the K. Vet. Acad. Haucll. 1842, 

 p. 174, and three new species added. 



The new species are : (1) Sorex (Crocidiira) Hedenlorgi, Snnd. " Totus 

 rufescenti niger, magnus ; " from Seuuaar, whence Kotschy also sent the 

 same species to the Vienna Museum, from which I procured the figure in 

 Schreber' s work. (2) Sorex fuhaster, Suud. " Pallide griseo fulvescens, 

 subtus ciuereo albus; deutibus intermediis, supra 3, secundo tertioque 

 aiqualibus. Cauda lougit. \ corporis." (3) Sorex (Crocidura) sericeus, Hed. 

 " Saturate cinereus nitidus, supra rufescente fuscus ; deutibus intermediis, 

 supra 3, secuudo, tertioque sequalibus ; cauda idtra corporis." The same 

 species was found by Kotschy in Kordol'an. 



With reference to my monograph in Schreber's work, I now add a few 

 remarks. Sorex crassicaudus, Licht., S. indicus, Auct. at least in part, S. 

 cra^icaud-us, Duv., S. giyanteus, Duv., and S. sacer, Ehr., I regard as only 

 one species. I have compared Lichteustein's original specimen of S. crassi- 

 cd/idtts with our own, and found complete correspondence in the dentition ; 

 in the colour, the former presents a light ferruginous shade on the back, and 

 especially on the head, more distinctly than in. our specimen, whilst the same 

 hue is still more apparent in our S. indicus. In colour, S. crassicaudus, Duv., 

 more nearly agrees with the specimens in our collection. When Duvcruoy 

 assigns to it only three intermediate teeth, it can only be owing to the fourth 

 small one having fallen out. The inconstancy of this tooth is shown by what 

 Puvernoy states of his S. giganteus.
