308 DR. T. S. COBBOLD ON HUMAN ENT020A. [NoV. 25, 



shrewd investigations of Dr. Weinland, made during his visit to 

 America. Unfortunately, no perfect specimen has been seen ; but, 

 from portions of at least six examples of the strobila, Dr. "Weinland 

 has clearly established its claim to be recognized as a good species. 

 The proglottides are short ; and " there is a yellowish spot, clearly 

 visible to the naked eye, situated about the middle of each joint, 

 which reminds us very much of the colour and situation of the genital 

 organs as known in Bothryocephalus" The reproductive orifices 

 occur all along one side of the worm ; and the eggs are unusually 

 large. Only one instance of the occurrence of this species is yet re- 

 corded ; and on this occasion they were obtained by Dr. Ezra Palmer, 

 in considerable numbers, from an infant nineteen months old. They 

 were expelled without medicine, their presence not having been even 

 suspected. (See D. F. Weinland's ' Essay on the Tapeworms of Man,' 

 p. 49 ; also his * Beschreibung zweier neuer Tsenioiden aus dem Men- 

 schen,' 1861, p. 8, t. 4.)
