164 TAPEWORMS OF HARES AND BABBITS— STILES. vol.xix. 



not feel justified in utilizing- liis work as basis for more than a provi- 

 sional generic diagnosis for Bertia until the type species of the genus 

 [B. studcri) can be studied more in detail. ISTor do 1 consider the data 

 at hand sufficient to justify a worker in suppressing Railliet's genus 

 Andn/a in favor of the earlier genus Bertia. From the very limited 

 material and data at hand, I am inclined to believe that AnopIocepJiahij 

 Bertia, and Andnja will all eventually be recognized as good genera, 

 established upon well-recognized anatomical characters, but for the 

 present, although Anoplocephala unquestionably stands, Bertia and 

 Andri/a can be accepted only as provisional genera, and as convenient 

 means of classification. The final acceptance of the genera can follow 

 only after examination of a larger series of specimens representing, 

 if i)OSsible, more species^ than are at present included under Andrya 

 and Bertia. 



To utilize the generic terms Andrya and Bertia provisionally is cer- 

 tainly better than to j)lace the forms in the same genus with Tcenia 

 solium.

During the proof reading of this revision an article has appeared by 

 0. Ph. Sluiter, describing a new species of tapeworm [Ta'nia plastiea) 

 from Galeopithecus rolans. Sluiter is inclined to consider this new para- 

 site as very closely related to Anoplocephala plieata, A. mamillana, and 

 A. perfoliata, all of which he retains as members of the genus Twnia. 



Unfortunately, several important points in the topographical anatomy 

 have been omitted by the author, but his description and figures show 

 that TfOiia plastiea is much more closely related to IMeyner's Ta'nia 

 {Bertia) mucronata than it is to the tapeworms of horses, on which 

 account 1 transfer it to the genus Bertia. From Sluiter's descri^jtion 

 and figures, the following specific diagnosis is written:

' Gottheil (1887) described two other cestodes, which may have some bearing upon 

 the question, with the followiug diaguoses: 



{T<vnia)'So. 1. Length 20 cm., breadth at largest segment 3.5 mm. Head globular, 

 four suckers, no rostellum, and no hooks. Neck extremely fine and filann-ntous — 2.5 

 cm. long. Proglottides slowly increase in size, greatest breadth being only attained 

 15 cm. from head. Sexual orifices at the sides. Segments oblong, 3.5 mm. by 0.75 

 nmi. From Macacjutj monkey {Macacits vjpiomolgiis (8cbreber) ). 



(Tania) No. 2. Length of largest specimen, 15 cm. Bnadth at largest segment, 

 8 mm. Head large and clubbed, four suckers, no rostellum or hooks; neck short 

 and thick; proglottides rapidly increase in size after the first inch and attain their 

 full diameter from head, 7.5 cm. mature proglottides. They overlap each other at 

 their posterior angles. Segments mature measure 8 by 4.5 mm. 



From Maeaijue monkey (Macucus cijnomologus (Schreber) ) and Weeping Capuchin 

 (Cebiis ((ipuchnoi (Linnteus) ). 



From the descriptions ami figures it is vcrj' possilde that these two forms are 

 an()i)locephaline cestodes, but Gottheil gives no characters which will aid in defi- 

 nitely determining the (juestiou at hand.
