104 PARASITES OF MAN 



under surfaces. When hardened in spirit the section of a 

 segment presents a three-branched appearance, the branches 

 being of unequal length, bat placed at equal angles. The 

 uterus sends vessels into the crest as well as into the sides of the 

 segment ; and the contained ova are exactly like the ova of an 

 ordinary Tcenia mediocanellata. Wedged in between, or 

 attached to, the segments here and there, is a stunted and 

 ill-shaped joint, with irregular and unequal sides. A mature 

 joint measures from five eighths of an inch to three quarters of 

 an inch in length, and about half an inch in breadth, and 

 the breadth or depth of the crest is usually one eighth of 

 an inch. 



" There are only two specimens that I can find on record at 

 all similar to the one here described, and both of these differ 

 from it in several important particulars. Kuchenmeister men- 

 tions, as a variety of Tcenid mediocanellata , a tapeworm sent 

 to him from the Cape of Good Hope by Dr Rose. This worm 

 possessed a longitudinal ridge, but he describes its mature 

 segments as 'extremely massive' more than an inch in length 

 and " in breadth. The genital pores, too, were irregularly 

 alternate, and not situated on the crest. On March 20th, 1866, 

 Dr Cobbold exhibited to the Pathological Society of London a 

 specimen of crested tapeworm which was discovered in the 

 museum of Middlesex Hospital, and to which he proposed to 

 give the name Taenia lophosoma (Ao^oc, crest ; <rcJ)ia, body). The 

 reproductive papillae were all on one side of the chain of seg- 

 ments, a peculiarity which entirely distinguished it from the 

 Cape of Good Hope variety of Kiichenineister. The head of 

 the creature was wanting. It will thus be seen that my 

 specimen does not correspond with either of these in the situa- 

 tion of the genital aperture. Here it is placed in the crest 

 itself, and not unilaterally, as in Dr Cobbold' s specimen, or 

 alternately, as in Kuchenmeister's. It further differs from the 

 Cape variety in the more moderate dimensions of its proglot- 

 tides. I have adopted, however, the name suggested by 

 Dr Cobbold in the communication referred to, inasmuch as it 

 sufficiently indicates the principal distinguishing feature of the 

 specimen. I may mention that Dr Cobbold saw the specimen 

 during his visit to Manchester, and that he regarded it as a 

 most remarkable and unique abnormality/' 



Further, in connection with abnormal cestodes, I may observe 

 that Weinland's case of a triple-crowned Cys'ticercus does not
