iirnieil with a double row <if about 800 ininule liookh-ts, of two 

 different sizes, the larger and smaller alternating, the larger 

 hooks 11 fi (Krabbe), 16 fi (Crety); smaller hooks 8 yu (Krabbe). 

 12 fi (Crety). In the earlier stages (see below T. pluriuncinata) 

 the suckers are armed with 6-8 concentric rows of instable 

 hooks which vary in size, but of similajr form. Suckers small, 

 0.186mni to 0.196nim in diameter. Neck present, thin. Anterior 

 segments 0.195mm broad by 0.40mm long (after Crety, 1890, p. 2. 

 the figures should undoubtedly be reversed); middle segments 

 2mni\ to 3mm broad by 1mm long; posterior segments 1.5mm long 

 by 2.5mm broad. Genital pores irregxilarly alternate in about 

 the middle of the lateral margin. Male genitalia: In posterior 

 portion of segment; testicles 15-20 in number, 45 ^ in diameter, 

 distributed regularly in median field; the common vas deferens 

 takes origin in about the middle of the segment, medium por- 

 tion more or less sim.ple, lateral portion convoluted; upon enter- 

 ing the cirrus pouch it swells into a vesicula seminalis, 53 ^ 

 long by 39 a broad, distinct only in the younger segments; cir- 

 rus covered with extremely minute spines, visible only with an 

 immersion lense. Female genitalia: In anterior portion of seg- 

 ment. Ovary median near anterior margin, at first transverse, 

 in the older segments it becomes globose and occasionally ir- 

 regularly divided into two lateral halves, connected by a me- 

 dian portion which leads into the oviduct; in middle proglottids 

 transverse diameter of ovary 0.186mm; oviduct short, runs dis- 

 tally; vitellogene gland distal of ovary, in youngest segments 

 appears as a globular sac next to ovary, in older segments 

 further removed from it and much smaller than it, occasionally 

 divided; vitelloduct runs from middle of vitellogene gland prox- 

 imally; shell gland very- small, situated between ovary and 

 vitellogene gland; vagina swells into a receptaculm seminis 58 

 /< by 39 /* near the ovary; uterus formis rapidly, suppresses 

 genital glands, eggs arranged 4-6 or more in egg capsules. Ova 

 28 n by 24 fi\ hooks of oncosphere 11 n to 17 ^ (Krabbe), 3 fi 

 to 4 /i (C^rety), oncosphere 11 fi.

Rlanchard (1891B. p. 434) looks upon Crety's Taenia pUiriiin- 

 oinata as synonymous with D. circumvallata. Crety's descrip- 

 tion of T. pluriuncinata is as follows:
