BIRD-INFESTING MALLOPHAGA OF JAPAN. 20~f 



II-IV segments successively shorter than the one preceding, the V segment 

 longer than the IV and about equal to the III. (In the female, the antennae 

 have the II segment longest, the I nearly but not quite as long as the II, 

 the III and the IV subequal and shortest of all, and the V slightly longer 

 than the IV).

Piaget, Les Pediculines, iHî-'o, p. 334, pl. XXVII, fig. 3. 

 Eight males, nine females and three youngs were collected from the 

 Temminck's cormorant, Phalacrocorax capillatus, shot in Prov. Shinano.

This species has previously been known only from several species of 

 cranes (Crus). It is a remarkable fact that I obtained a female specimen 

 from the mallard, Anas bosclias, captured in Prov. Shinano. The measure- 

 ments of my specimen agree well with those given by Taschenberg, but 

 are considerably larger than those given by Piaget. It may be that the 

 latter auther had before him an immature specimen.
