LARVAL DIBOTHRIA. 



Cestode larvae, which appear to belong to the genus Dibothrium, 

 were found in three of the Bermuda fishes. 

 JBodianus fulvus punctatus. 



Jul}'^ 23, fragment. This specimen was finely and transversely 

 wrinkled and the parenchyma contained numerous calcareous bodies. 

 It resembles the posterior end of an immature Dibothrium.

July 11, one. This specimen was exceedingly variable in shape, 

 and there were no definite organs. The anterior end was densely 

 covered Avith short spines, and there was an aperture in front into 

 which the anterior end of the bod}^ could be inverted. As the worm 

 became quiescent under the cover glass the anterior end was perma- 

 nently retracted and the worm assumed a vase shape. 

 Paranthias furelfer. 



July 29, numerous cylindrical cysts, most of them dark brown, and 

 some of them degenerate. One of the larger cysts measured 22 mm. in 

 length and 2 mm. in diameter. The larva measured 14 mm. in 

 length and 1.5 mm. in diameter. It was corrugated transversely, 

 slightly inverted at the anterior end and had a small pore at the pos- 

 terior end. There were numerous calcareous bodies in the paren- 

 chyma. The smaller cj'sts were from 3 to 5 nmi. in length. 



In one of the larger specimens numerous glandular bodies were 

 seen. Similar structures have already been noted by me." These 

 structures have been made the subject of special inquiry by Pintner.* 



The generic character of these larvi^e is uncertain. 



CESTODE LARViE, CYSTS, ETC. 



Larvae too innuatuie for identification and C3^sts with indefinite or 

 indeterminable contents are here noted: 

 Hathystoni a strlatuvi . 



July 17, one blastocyst from viscera; too immature for identification. 

 H3e,mulo7i fldvolineatwin . 



eFul}^ 27, one cyst with blastoc^^st, but no larva recognizable. 

 Neom sen is synagris. 



July 18. Aml)er-colored cj^sts of uncertain origin, with waxy con- 

 tents, were found in the stomach wall of the largest fish of the three 

 examined. These cysts ma}^ be due to nematodes. 

 Ocy lines chrysurus. 



eluly 7, one small blastoc3'st, white, variable, but for the most part 

 P3a'iform; no larva in it. Length 1.5 mm., breadth 0.15, tapering to 

 0.05 mm.
