This genus was proposed recently in a preliminary 

 cation by Diamare. A more complete Isnowledge of the worm 

 is necessary before it will be possible to judge whether the 

 genus is well founded or not. No member of the genus has yet 

 been recorded in domesticated fowls, but the type and only 

 species Is found in the flajmingo. 



6. AMABILIA LAMELUGERA (Owell, 1835) Diamare, 1893. 

 1885, Taenia la,melligeia Owen.) 

 (PI. II, figs. 18-20.) 

 Diagnosis: Strobila 120nim to 170mm long, 10.5mm broad, 2.1mm 

 thick. Head almost globular; rosteUum cylindrical, obtuse; 

 armature? Neck absent; segments very short. Genital pores 

 double; ovary single and median. Ova segregated near base 

 of rienis. 

 Hosts: Flamingol (Phoenicopterus antiquorum). 

 Geographical distribution: ? by Sykes; France by Gervais; ? 

 Sardinia (? Cagliari) by Ficalbi. 



II. Genital pores single. Suckers armed or unarmed. 



Hymenolei.is. Did anntaenia. 



Genus HYMENOLEPIS Welnland, 1858. I 



(1S58, Diplacanthus Weinland (nee L. Agassiz).) 



Diagnosis: Strobila small (filiform). Head small, provided 

 with a retractile rostellum, well developed and armed with a 

 single crown of 24-30 booklets, or rudimentary and unarmed. 

 (Neck long. Segments serrate, much broader than long, rarely 

 less than 150 in number.) Genital pores marginal, sinistral, 

 the female surface of the proglottid representing ventral. 

 Testicles few, generally 3 in each segment, one left and two 



iQwen states that his specimens were collected by Lieuten- 

 ant-Colonel Sykes "in a Flamingo, Phoenicopterus ruber, 

 Linn." Diamare states that his own specimens were collected 

 by "Professor Ficalbi, della R. Universita di Cagliari," from 

 •■Phoenicopterus roseus." According to Dr. T. S. Palmer, the 

 Old World flamingoes are P. antiquorum Temm. (syn. P. roseus 

 Pallas), P. erythraeus. and P. minor; the New World flamin- 

 goes are P. rtiber Linn., and P. ignipalliatus. In Owen's time, 

 however, all flamingoes were included under the name P. ruber 

 Linn. As it was not stated where Sykes collected his mater- 

 ial it is impossible to determine the host species definitely, but 

 upon Dr. Palmer's advice I take P. antiquorum as host.
