426 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 2 



Tubovesicula Yamaguti, 1934). Yamaguti has described a species of 

 Lecithocladium without denticulations, but even so the genus differs 

 from Mecoderus in body form, male duct, location of genital pore, and 

 form of sinus sac. Erilepturus has suckers distant from one another and 

 a tripartite seminal vesicle as well as a different body shape. Tubovesicula 

 has a different body shape, a long continuous prostatic gland, tubular 

 seminal vesicle, separated testes, and shorter vitelline lobes. It is, how- 

 ever, probably the most closely related genus. Stomachicola is very differ- 

 ent in body form, development of ecsoma, and location of the gonads in 

 relation to the acetabulum. 



Sterrhurus fusiformis (Liihe, 1901) 



Host : Muraena clepsydra Gilbert 



Location : Stomach 



Locality: Cape Elena, Ecuador 



Number : Several specimens in both of 2 hosts examined 

 These rather large sterrhurids (3.051 to 4.434 in length by 0.864 to 

 1.067 in width) agree almost perfectly with specimens from Gymno- 

 thorax funefris Ranzani and Gymnothorax morinza (Cuv.) at Tortugas. 

 Linton (1910) reported them from Tortugas. Both the Atlantic and 

 Pacific forms agree in detail with Looss' (1907) description of S. fusi- 

 formis from Conger conger in the Mediterranean except that the eggs are 

 slightly smaller and more narrow. Specimens from both Tortugas and 

 Ecuador have eggs measuring 14 to 18 by 9 to 12 /i as compared with 20 

 to 25 by 17 to 19 ^ reported by Looss.

Caulolatilus sp.
