160 TJPKIVORMS OF HARKS IXI) R.I BBJTS— STILES. 



unarmed, about 0.5 mm. in diameter; rostellum not observed; neck 

 liliform. Segments 500 to SOO in number, quadrate, broader than long; 

 gravid segments may attain 8 mm. in breadth. Genital pores in about 

 the middle of the margin or in distal half of the margin, irregularly 

 alternate, but for the greater part unilateral. ]\Iale organs: Testifies 

 scattered through the entire breadtii of the median field; cirrus pouch 

 0.4 to 0.48 mm. long by 0.14 to 0.16 mm. broad, quite muscular, and con- 

 tains a distinct vesicula seminalis; prostata rouiul. Female organs: 

 Vagina distal of cirrus swelling to an elongate receptaculum seminis 

 ventral of vas deferens; ovary near median line in pore side of median 

 field: uterus forms a network in median field, but as the ova develop 

 the boundaries of the meshes become quite indistinct. Ova 48 to GO /i 

 in diameter; pyriform body 20 /< broad by 32 to 44 // long. Calcareous 

 bodies become numerous in distal segments.

Genus BERTIA, R. Blanchard, 1891. 



1891, Bertia, R. Blanchahd, Moui. Soc. zool. France, IV, pp. 18t>-li»6. Type, Bertia 

 stiideri, E. Ulancliard. 



Provisional diagnosis. — Anoplocephalinii?, with segments broader than 

 long. Genital pores regularly or irregularly alternate. Uterus (in all 

 cases'?) a transverse tube with proximal and distal eg'^ pouches; geni- 

 tal canals pass dorsally of dorsal and ventral canal and lateral ner\e 

 trunk, but in the two cases at least ventrally of dorsal longitudinal 

 nerve; distinct prostatic gland wanting. Dorsal canal dorsal to dorso- 

 lateral of ventral canal. Egg with well-developed pyriform body. 

 Calcareous corpuscles i)resent or absent. Ho^ts: Primates and rodents. 



Typt:—B. stiKhri, li. Blanchard, 1891. 



Two years prior to the publication of the genus Andrya by Railliet, 

 E. Blanchard, in 1891, proposed the genus Bertia for auo])locephaline 

 cestodes with alternate genital pores, taking 1>. studeri from Anthro- 

 popithecus tro</lodijtc.s as type of the genus; as second si)ecies of the 

 genus he described 7>. satyri. 



Unfortunately, on account of paucity of material, Blanchard was 

 unable to give the anatomy of the type species, so that the generic 

 diagnosis was based chiefly upon external characters. Ilis original 

 diagnosis reads as follows : 



Caput crassum, 8ul>si)liaericum, rostro aculeisque careiis, acetabiilis eilipticis, in 

 dua paria valde distaiitia dispositis. Colluui breve, propre tain lar,i;uin quani caput. 

 Corpus e permulti.s aunnlis brevissimis latiscjue, imbricatis, coustaus. Pori geui- 

 tales margiuales, tcnuissiiui, ab uuo auuulo ad alteruiii plus minus regulariter alter- 

 nantes. In auuulo pernuxturo, ova in plures fasciculus regulaics, transverse dia- 

 positua, collecta. Oncosphaera pyri forme api)aratu ciicumdata. luvolutio ignota. 



From Blanchard's descriptions of the species the following may be 

 taken as provisional specific diagnoses.
