97 



species is recognized, and there has been practically no difference of 

 oi)inion on the snbject of species since the publication of that treatise, 

 thongh all the names appear in the uncritical compilation of Fitzinger 

 in 1809. 



The generic name Condylura was replaced by Ehinasfer by Wagler 

 in ]8o0,because he considered the former appellation misleading. " Wie 

 bekannt," he remarks, "ist der Schwanz dieses Thieres ^'oIlkommen 

 eben."^ Gray employed the name Astromyctes for the genus, in 1843, in 

 his List of Mammals in the British Museum, but credits it to Harris, 

 who did not use it. A new name — Astromydes — was coined by Blyth 

 in 18G3. 



MEASUREMENTS. 



Collector's measurements of six specimens, both males and females, 

 from Locust Grove, IS^ew York, in Dr. Merriam's collection, gi\Q an 

 average of 202 mm. for the total length (including the tail), with a maxi- 

 mum of 212 mm. and minimum of 200 mm. 



This average, it will be observed, is higher than that given by the 

 alcoholic specimens.
