1012: .PARASITES OF MAN 



a drawing by Dr Wyman." It is further stated that the infant 

 was nineteen months old, and that the worm was discharged 

 without medicine, its presence having never been suspected. It 

 was presented by Dr Ezra Palmer in the year 1842. On 

 examining the fragments, Dr Weinland found, instead of a 

 solitary specimen, at least six different tapeworms, all of them 

 being referable to a hitherto undescribed species. There were 

 no heads ; nevertheless, it was ascertained that the worms varied 

 from eight to twelve inches in length, the joints or segments 

 being very broad, and at the same time narrowed from above 

 downwards. The parasite was named " the spotted tapeworm," 

 in consequence of the presence of yellow spots near the middle 

 of the joint. They represent the male organs of reproduction, 

 the outlets of which, as in my T. lophosoma, occur all along one 

 side of the body or strobile. In Weinland's estimation this 

 parasite forms the type of a new genus which he calls Hymeno- 

 lepis. A full account of the worm is given in his well-known 

 essay (1. c., Bibl. No. 2). 



Tania abietina and other varieties. I can only notice very 

 briefly certain cestodes which either present malformations or 

 which may be regarded as mere varieties. First in this series is 

 Wemlsnid'sT.abietina. No one who has studied his 'Beschreibung 

 aweier neuer Taenioiden aus dem Menschen/ Jena, 1861, can 

 doubt that it is a mere variety of T. mediocanellata. The 

 monstrosity described by him as referable to T. solium must also 

 be referred to the beef tapeworm. The variations in the cha- 

 racter of cestode proglottides is practically infinite. A museum 

 might be filled with them. Most common with T. medio- 

 canellata, these varieties more or less prevail with other species. 

 Thus I have seen them in Taeniae and Bothriocephali alike. I 

 have obtained segments of T. mediocanellata having sexual 

 outlets on both sides of the pro glottis, so regularly disposed in 

 a few segments as to suggest the notion of a new species. The 

 coalescence of several segments into one compound segment is 

 frequent, but the most remarkable specimen that I have seen is 

 one contained in the museum of the Royal College of Surgeons. 

 In the old Hunterian catalogue the specimen is described as 

 " two joints of the Tcenia 8oliuin y with a number of orifices in 

 unequal series on either side." As stated in the new catalogue 

 of the series, prepared by myself, the "lower segment is furnished 

 with twenty-two sexual orifices, one of which is situated in the 

 central line" on the ventral surface (as in Bothriocephali).
