DE. T. S. COBBOLD ON SCLEEOSTOMA SYNGAMUS. 305 



ciety, Ins paper being entitled " x\ccovmt of a species of Faseiola 

 which infests the trachea of Poultry, with a Mode of Cure." Mon- 

 tagu does not appear to have been aware of the existence of any 

 previous record on this subject, as we gather from an editorial 

 note appended to his memoir in the first volume of the Wernerian 

 Society's Transactions. Fortunately our author gave a scientific 

 description of the parasite, which consequently led to its being 

 specifically noticed, under various titles, in the systematic works 

 of Rudolphi, Dujardin, and Diesing ; but by far the most elabo- 

 rate accounts of this animal are due to the writings of Von Siebold, 

 whose name legitimately stands at the head of helmintliology. 



To avoid further prelude, I subjoin a complete synonymy, with 

 references : —

If, as I surmise, the above synonyms all refer to the same 

 species of worm, this parasite has been found and recorded as 

 occurring in the trachea of the following birds, namely : the Tur- 

 key, Domestic Cock, Pheasant, Partridge, Common Duck, Lap- 

 wing, Bhxck Stork, Magpie, Hooded Crow, Green Woodpecker, 

 Starling and Swift. I do not doubt that tliis list might be very 

 much extended if our British ornithologists would favour us with 

 their experience in the matter. Hithei'to I have been surjjrised 

 to find how few of those to whom I have mentioned the subject 

 appear to be acquainted either with the nature of the parasite or 

 with the various methods to be adopted in curing the disease to 

 which its presence in the windpipe gives rise. In view, therefore, 

 of adding something to our knowledge of its structure, and, more
