Specimens Jrom Merluccius bilinearis. — I have recorded this species 

 under the name Dibothrium angustatum (Rudolphi) previously from 

 this fish« (U.S.N.M. No. 8868). 



Specimens jrom Oligoplites saurus. — Four small immature strobilae 

 were taken from one fish July 14, 1924. Measurements in balsam: 

 Length 7 mm.; breadth 0.31 mm.; scolex length 1.4 mm., breadth of 

 terminal disk 0.14 mm., near anterior end 0.2 mm., near posterior end 

 0.13 mm., at posterior end 0.14 mm.; first segment length 0.14 mm., 

 anterior breadth 0.14 mm., posterior 0.15 mm. (U.S.N.M. No. 8869). 



Specimens jrom Palinurichthys perciformis. — Recorded from this 

 fish by me under the name Dibothrium punctatum (Rudolphi).^ It 

 has also been recorded from Woods Hole by Cooper.^ Two slender 

 immature specimens were taken from this fish on August 17, 1904; 

 maximum length 115 mm., maximum breadth 1.6 mm.; most of the 

 segments longer than broad (U.S.N.M. No. 8870). Also two, each 

 about 12 mm. long, segments irregular, on August 20, 1910. 



Specimens jrom Paralichthys dentatus. — This species under the 

 name Dibothrium punctatum (Rudolphi) has been recorded by me ^ 

 and by Cooper.^ It was collected on three dates in August in two 

 different years. On one date the record is one and fragments; on 

 another, one, length 40 mm.; and on the other, one, length not given. 

 Fragments, apparently of the same strobila, have an aggregate length 

 of 150 mm.; maximum breadth 3 mm.; first segments slender, longer 

 than wide; ova 0.06 by 0.03 mm. (pi. 61, fig. 10) (U.S.N.M. No. 8871).
