NOTE XX. 

 A NEW FLEA FROM KERGUELEN-ISLAND 



DESCRIBED BY 



Dr. O. TASCHENBERG. 



Pul ex Kerguelensis, sp. n. 



Body elongate, of a yellowish brown colour. The in- 

 clination of the upper surface of the head commences im- 

 mediately in front of its hind margin ; on a level with 

 the first joint of the antennae this inclination suddenly in- 

 creases. In front of the point of insertion of the maxil- 

 lary palpi the head forms an inconspicuous tooth-like 

 projection. The joints of the maxillary palpi are of about 

 the same length. The triangular maxillae are pointed 

 and rather long. The groove for the antennae is so situ- 

 ated that its hind margin divides the lateral surface of 

 the head into an equal anterior and posterior half. The 

 eye , which is comparatively light coloured , is situated 

 very low , touching the inferior border of the head. The 

 antennae are very similar to those of Pulex glohiceps Tschb., 

 only the strong bristles on the upper margin of the second 

 joint are absent. The thoracical segments are rather broad. 

 The legs slender , with narrow tarsal joints ; they carry 

 numerous spines and are covered with a dense pubescence. 

 The latter is also uncommonly dense on the rest of the 

 body and therefore very characteristic for this species. On
