Drepanidotaenia heraignathi, n. sp. 



Length 1 — 2*2 centimetres; breadth, in the middle of the 

 body, 2 millimetres. Head flattened and compressed, rostrum 

 with a crown of ten hooks; each hook 18 — 23^ in length, and 

 with but a slight trace of the inner limb of the forked base. 

 Neck short. The first segments are short, but they very soon 

 (eighth or tenth) show traces of reproductive organs. Genital 

 pore unilateral. The posterior limit of each segment is sharply 

 defined, and forms an angle of about 45 degrees with the 

 sides. Egg spherical, diameter about 40 — 50 ju. The three 

 pairs of embryonic hooks measure about 20 ju each in length. 



Habitat: Hemignathus procerus. Sandwich Islands, iu 

 the intestine. 



Note 1. — In a paper which I published in this JournaP last 

 year on Arhynchus hemignathi I stated tliat the parasites 

 were found ^' adhering lightly to the skin around the anus.'^ 

 I had this description from Mr. Perkins^ and I understood it 

 to imply that the parasites were outside the body. In this I 

 find I was mistaken; and fearing that others may be under a 

 similar misapprehension, I am writing this note to say that 

 they occur inside the body-cavity in the angle where the rectum 

 joins the external skin. 



Note 2. — Mr. Perkins has also given me two or three speci- 

 mens of a tapeworm from a Loxops, sp. This bird, like the 

 Hemignathus, is a member of the family Drepanididse, which 

 is confined to the Sandwich Islands. Unfortunately the 

 specimens are without their head, and I am unable to identify 

 them. They differ markedly from the Drepanidotaenia de- 

 scribed above.
