NO. 1560. PARASITES OF BERMUDA FISHES— LINTOX. 113 



defenis distinct along the median line anteriorally, not so distincth'^ 

 seen near the testes as shown in the sketch. Other genitalia not quite 

 satisfactoril}' made out. What were taken to be the testes are two 

 elongated, lobed bodies, one following the other, but diagonally placed, 

 and situated near the posterior end, but in front of that portion of the 

 uterus which contains the greater part of the ova. Another organ, 

 probabl}^ the ovary, lies beside the anterior testis. Clusters of deeply 

 staining bodies, which extend from about the anterior sixth to a point 

 a little in front of the middle, ma}^ possibh^ be the vitellaria, although 

 some of them appeared to be folds of the intestinal rami. 



Dimensions of specimen mounted in balsam, in millimeters: Length 

 12; diameter of anterior projection containing oral sucker 0.14; diam- 

 eter of body, anterior 0.33, at ventral sucker 0.48; anterior sucker, 

 length 0.14, breadth, anterior 0.08, posterior 0.06; genital papilhi, 

 length 0.04, breadth 0.05; ventral sucker, length 0.07, breadth 0.11; 

 length of esophagus 0.3; distance of ventral sucker from genital papilla 

 0.46, from anterior end 0.63; ova 0.018 by 0.012. Length of living- 

 worm 14; breadth 0.2 to 0.5. 

 From Eplnejphelus striatus. 



Jul}" 14, one. 



I do not find any distome at all resembling this in Pratt's Synopsis. 



UNDETERMINED DISTOMES. 



The following distomes are not given specific names on account of 

 either the small amount of material in each case or its unsatisfactory 

 condition. 



It is hoped that the notes which it was possible to make, together 

 with the naming of the host in each instance, will prove to be of use 

 to future investigators. 

 DtHtoinvm, species from Serlola fasclata. (Plate VII, figs. 55, 56.) 



July 31, two. These worms being immature and partly macerated, 

 but little of their anatomy could be made out. Testes, two, globular, 

 near together, one following the other and near the posterior end; 

 ovary small, globular, in front of anterior testis and separated from 

 it by a distance about equal to the diameter of the testis. The ante- 

 rior end of one was retracted, and there was a small mass of black 

 pigment in each between the oral and ventral suckers. The vitellaria 

 were not distinct. The character of the intestines could not be made 

 out. Each of the specimens was linear and smooth. 



Dimensions in millimeters, life: Length 3.30; breadth at ventral 

 sucker 0.40, behind ventral sucker 0.30; diameter of oral sucker 0.19, 

 of ventral sucker 0.30. 



Dimensions of specimen in balsam: Length 2.55, breadth 0.25; 

 diameter of oral sucker 0.18, of ventral sucker 0.24; distance of ven- 

 tral sucker from anterior end 0.37, distance of posterior testis from
