CESTODES. 



1. Scolex polymorphus Rudolphi. 



1902. — July 14; few; bothria with two costse and rudiment at anterior end, suggesting the loculi 

 which occur at the anterior end of bothria in Echeneibothrium and Acanthobothrium; no red pigment. 

 My attention was called by Mr. Gudger to some minute oval Forms from this same lot which proved to 

 belong here. They were similar to minute specimens found in Lagodon and others; length 0.09, 

 breadth 0.06 mm. These minute tonus contained calcareous bodies of relatively large size in the 

 parenchyma. July 15; large numbers, minute. July 16; immense members, length 0.06 when 

 contracted, 0.12 when extended, heads relatively large, eases of constriction making pseudo-segments 

 noted in this lot. July 17; very numerous, small. July 29; very numerous, 0.01 mm. in length. Aug. 

 4; few, comparatively large. 

 •_'. Khinebothrium s|>. [Fig. 75.] 



t'vsts with blastocysts containing larva which are identical with No. 4 under Opsanus tau, but do 

 not occur in felted clusters so commonly as in that host. 



July 7; few. July it; 24. July I'M, 25; several. Aug. 4; few. Aug. 6; a large number on and 

 in the liver, cithers on viscera; as in the toad-fish, so in this case the blastocysts were much 

 elongated at the posterior ends, which were felted together in clusters. No cases were found which 

 demonstrated budding of blastocysts, although the manner in which the blastocysts are associated 

 together would suggest that as a possible explanation of the frequent occurrence of clusters of this 

 parasite. A.ug. 20; several. 



3. Tetrarhynchus bisulcatus Linton. 



July 17; 1 scolex, encysted on viscera. 



TEEMATODES. 



4. Distn, iinui sp. 



Aug. !l'; I; length 1.65 mm.; breadth 0.63 mm. ; agrees with No. 4 under Spheroides maeulatus. 



5. Dislomum ralde-inflatum Stossich. 



Aug. 12; 1; encapsuled on viscera. 



PROTOZOA. 



ii. Gregarinet. 



July 17. The testis of a pipe-fish which was infested with what was taken to be a gregarine 

 parasite was brought to my table by Mr. E. W. Gudger, who was working on the development of the 

 pipe-fish. ( In account of the large amount of material to lie looked over on this date, I was not able 

 to give this much attention. Aug. 6; small, irregular gregarine-like forms observed in testis.
