T^NIOID CESTODES OP NORTH AMERICAN BIRDS. 21 



species described by Weinland. Furthermore, it appears upon com- 

 paring these specimens with Fuhrmann's (1907b, p. 521) description 

 and figure of Fuhrmannia hrasiliensis from Picus, species, Brazil, 

 incompletely described by Parona in 1901, that the latter is of the 

 same species. 



In accordance with the International Code of Zoological Nomencla- 

 ture the name Liga punctata is invalid, since prior to the publication 

 of this name the species to which it belongs was referred to under the 

 name of Tmnia punctata^ which is a homonym of Twnia punctata 

 Rudolphi, 1802. This reference (Weinland, 1856a, p. 25) is as fol- 

 lows: 



In another and new species of tapeworm, the Twnia punctata Weinl., found in 

 the golden-wiuged woodpecker, he had observed the embryo just hatching. The 

 shell of the egg of the worm has two processes, each terminating in a large 

 ball ; the embryo is provided with six spines. 



Tmnia punctata Weinland, 1856, being a homonym, and Liga punc- 

 tata accordingly invalid, the species takes the next available name, 

 which is Liga brasiliensis (Parona, 1901).

Fuhrmann describes Fuhrmannia hrasiliensis as a very small ces- 

 tode, consisting when mature of only about 16 proglottids ; its length 

 scarcely 3 mm., its greatest breadth 0.5 mm. The scolex has a diam- 

 eter of 0.39 mm., suckers 0.15 mm. The rostellum is armed with a 

 double crown of hooks, which are almost exactly similar in shape. 

 Each crown consists of 10 hooks, the larger of which measure 0.043 

 mm., the smaller 0.039 mm. in length. Genital pores regularly alter- 

 nate. Testicles 12 to 14 at posterior border of segment. Cirrus 

 pouch small, pyriform. Cirrus surrounded at its base by a crown of 

 long fine spines, forming in the genital cloaca a small dark staining 

 cone. The last segment is entirely filled with the sac-like uterus and 

 measures 0.7 mm. in length and 0.5 mm. in breadth. Oncosphere 

 0.027-0.03 mm., outer membrane, 0.048 mm. in diameter. The outer- 

 most shell appears to have not yet developed. 



The specimens upon which the following description is based were 

 collected from the small intestine of a golden-winged woodpecker 

 {Golaptes auratus) killed near Bowie, Maryland. They are pre- 

 served in the Helminthological Collection of the Bureau of Animal 

 Industry, No. 4577.
