consisting of very dark lateral border and large trans-

 middle line, others not meeting; an uncolored, median, 

 longitudinal line interrupted on segment 6; on ventral 

 side transverse blotches continuous across all the se£- 

 ments; anterior and posterior margins of each segment 

 narrowly uncolored; an ill-defined stigmatal uncolored 

 spot on segments 2-7 ; segment 8 conical, much narrower 

 than segment 7, and segment 9 very short and narrow, 

 two-pointed, each point bearing two strong hairs ; sparsely 

 haired; posterior lateral angles of segment 1 with one 

 hair, of segments 2-4 with two hairs, of segments 5-6 

 with three hairs, of segment 7 with four hairs; segment 

 8 with two strong hairs near anterior lateral angle, two 

 shorter hairs on side and three separated, strong, pustu-

Taken from four of five specimens killed of the Cal- 

 ifornia Brown Pelican, Pelecanus californicus (Bay of 

 Monterey, California), and on two White Pelicans, Pele- 

 canus erythrorhynchus (Lawrence, Kansas), the parasites 

 numerous on the birds. Nitzsch's specimens were taken 

 from Pelecanus onocrotalus (locality?). My specimens 

 show distinctly the short forked projection on the first 

 segment of the antennas of the male, the character noted
