and Australasia : The specimens (</" and $) described respectively as 

 jimbriatus and borealis by Kramer and Neuman were found on BERING 

 Island, Bering Sea, by the Vega Expedition ; we are indebted to the 

 U.S. Department of Agriculture for a typical specimen (N. 714, ?) of 

 putus from Bering Island. Neumann (1899, p. 127) records (?, o) the 

 tick from Campbell Island, S. of New Zealand (Filhol coll., Paris 

 Mus.) aud from King Island (Tasmania ?). The types (o s) described 

 by Pickard-Cambridge (1878, p. 222) were found on Pygosceles taeniatus 

 and in rock crevices, Kerguelen Island, Indian Ocean, by A. E. Eaton 

 (Transit of Venus Expedition). We have received a °. taken from 

 a wild duck (N. 617 ; no particulars, ex N. C. Rothschild coll.).

 ( ? capitulum in dorsal aspect, tarsus 1, scutum, coxa I, drawn from a 

 mounted specimen aud consequently difficult to recognize from the figures — 

 that of the capitulum being especially misleading) : recognizable from 

 tarsus 1, coxa I and scutum.

 Note : As will be seen by reference to /. neumanni N. and W. (p. 217), there has 

 been considerable confusion about this species. We have examined the type of Ixodes 

 parvirostris (Nn. coll.) and of /. eudyptidis var. signata (Hamburg Mus.), and find 

 them to be identical with a mutilated ? specimen (identified by Banks as signatus) 

 from Pacific Grove, California (U.S. Dept. of Agriculture), and with specimens of our 

 own (N. 290) from the same locality as the last. Our figures are drawn from the 

 specimens ( ? , o) in the Hamburg Museum and (L) from California. 



Male : unknown. 



Female (Figs. 261, 262) : Body (6 x 35 mm. when replete), elongate, 

 yellow (in young specimens). Scutum: 17 x 1"2 mm., yellow-brown 

 or maroon, subject to considerable variation both of shape and of 

 texture, normally long-oval, with rounded sides and somewhat pointed 

 posterior angle, but sometimes considerably narrower and somewhat 

 angular laterally ; anterior border ill-defined, scapular angles prominent 

 and often slightly divergent, so that the scutum is somewhat narrower 

 immediately behind them ; some large confluent punctations or rugosities
