Described from 10 cf and 1 % taken by Mr C. C. Dobell from 

 Tragulus memmina (the Mouse Deer), at Colombo, Ceylon, 3 viii. 1909, 

 and named H. longipalpis by Warburton (1910). The ^ was described 

 before as H. aculeata by Lavarra (1905) ; the latter name has, therefore, 

 priority. Lavan-a's specimens (16 </) were found on Ti'agulus memmina 

 Bodd. in the East Indies, the host, which died in a menagerie, having 

 been purchased by the Zoological Museum, Rome. A specimen kindly 

 presented to us by the author (N. 2731, co-type) agreed fully with the 

 foregoing description of the ^ . 



This remarkable species, though undoubtedly a Haemaphysalis, has 

 the abnormal character of palps much longer than broad. It belongs 

 to the H. bispinosa group.
