the level of the middle of the ovary. Coils of uterus extend from

Fig. 28. 



1899. Ascocotyle minuta Looss, lS99f>, pp. 585, 689-699, 700, 701, pi. 26, fig. 

 23 (in dog, cat and Ardea cinerea; Egypt). 



Specific diagnosis. — Ascocotyle : Length, about 0.5 mm.; maximum 

 breadth, about 0.22 mm.; neck in extended condition may be 

 reduced to a thickness of 17 \i.. Oral sucker about 40 pi. in diameter. 

 Circumoral spines cylindrical, abruptly pointed posteriorly, 18 to 

 20 in number, arranged in a single crown ; dorsal spines, 13 [;., ventral 

 spines, 12 [x long. Oral cecum, 50 to 66 ix long. Ventral sucker, 

 45 to 56 [x in diameter, in the beginning of the broader, posterior 

 portion of the body. Pharynx, 41 [i long by 24 pi wide, almost 

 cylindrical, lies in the posterior region of the neck, a short distance 

 in front of the bifurcation of the intestine. Intestinal ceca short; 

 do not extend posterior of the region of the ventral sucker. Testes 

 very small, oval, long axis transverse. Ovary in front of right 

 testis and of similar size. Seminal receptacle in median line in 

 front of testes. Vitellaria in lateral fields in posterior end of body, 

 not reaching the level of the ventral sucker anteriorly. Eggs with 

 relatively thick yellowish-brown shells, 23 to 24 \i long by 14 ]x wide. 



Hosts. — Dog; cat; Ardea cirierea. 



Location. — Middle portion of small intestine (dog, cat), intestine 

 {Ardea). 



Localities collected. — Egypt (Looss) ; Brazil (by Faria, according 

 to Travassos, 1916). 



ASCOCOTYLE ITALICA Alessandrini. 1906. 



1906. Ascocotyle italica Alessandrini, 1906, pp. 221-224 (in dog; Italy). 



Specific diagnosis. — Ascocotyle: According to Alessandrini, very 

 similar to A. minuta except in following characters: Dorsal lip ap- 

 parently not projecting anteriorly as a triangular process. Intestinal 

 ceca extend much behind the level of the ventral sucker, apparently 

 reaching the excretory vesicle. Oral cecum much less than half the 

 length of the prepharynx. Vitellaria not arranged in small scattered 

 acini, but in two solid masses irregularly situated in the posterior 

 part of the body. Testes much larger and much closer together. 

 Eggs very numerous; uterus with mnnerous coils closely pressed to- 

 gether filling the space between the ventral sucker and testes.
