On an Unnamed Species of Cqvvws. 195 



Flahelligera Claparedii, which differs from S. diplocha'itos 

 chiefly in liaving 23-25 notopodial bristles, 1-2 ventral hooks, 

 and different forms of papillaj. Now if in the Millport 

 specimens the short notopodial bristles be counted in addition 

 to the long ones, this would make the number the same as in 

 St. Josepli's species, and the number of ventral hooks is the 

 same. It seems probable that S. diplochattos is a very 

 variable species, exhibiting a strong tendency to run into 

 local races, and that the three " species," S. diplocha'itos, 

 S. offinis, and S. Claparedii^ are only varieties of the same 

 species. 



EXPLANATION OF PLATE IV.

 chattos, t^howing eleven long bristles, represented as if cut 

 short, and ten short bristles scarcely projecting from the surface 

 of the papilla. The line a a represents the outline of the papilla.

XXIII. — On an Unnamed Species of Cevvus/rom Turkestan. 

 By R. Lydekker. 



On pages 108 and 109 of my work entitled * The Deer of 

 All Lands ' brief mention is made of a stag recently (and 

 perhaps still) living in the zoological gardens at Moscow, 

 which at the time in question I was unable to refer to any 

 known species, though I refrained from giving it a scientific 

 name till further information was obtained. The specimen, 

 of which a figure, copied from a photograph, was given, was 

 reputed to have come from Turkestan, and in the characters 

 of its antlers, of which a cast pair are in the possession of the 

 Duke of Bedford, is evidently allied to the shou {Cervus 

 offinis) of the district north of Bhutan. 



Recently the Duke of Bedford has received a stag from the 

 neighbourhood of Tashkend, which is now living in the park 

 at Woburn Abbey, and which, although it has at present no 

 antlers, I have no hesitation in referring to the same species
