J-J74 BULLETIN OF THE BUREAU OF FISHERIES. 



These dolphins were taken by the Fisheries steamer Fish Hawk about 28 miles off I lape Lookout. 

 They a<ree with descriptions of this species in length of maxillary, profile of head, number of spines 

 in dorsal and anal tins, coloration, and size. Length 20 to 24 inches. 



NEMATODES. 



1. FUaria galeata sp. nov. [Fig. 20.] 



See No. 1 under Sphyrna tiburo (figs. 17-19). 



Numerous fragments from stomach. These worms have the appearance of having been introduced 

 into the stomach of the dolphin along with some host in which they were adult. A number of these 

 were males with only tin- posterior ends preserved. These fragments, while agreeing closely with the 

 species described from the bonnet-head shark, presenl some differences. The posterior ends were 

 simply curved in a helix instead of a spiral. This, however, may he accounted for by the flaccid con- 

 dition of the specimens, due. presumably, to the digestive fluids of the dolphin. 



The long spicule of the male (fig. 20) was winged at the distal end so as to resemble the fluke of 

 an anchor. 



The fragments of females contained ova in which young had already developed. It should he 

 noted that the ova had lain in sea water for two days before they were examined. They varied some 

 what in size. The best formed ova measured 0.032 by 0.018 mm. in the two principal diameters. 



CESTODES. 



2. Scoiex polymorphic Rudolphi. 



Numerous, small, but with two costfe developed on the bothria. 



:-!. Blastocyst. 



One, with no indication of larva. It resembles the kind of which Rhynchobothrium speciosum is a 



type. 



TREMATODES. 



4. Distomum lornatum Rudolphi. 



Numerous, mainly from the stomach; 247 were counted. 



5. Distomum monticellii Linton. 



A few smallish, immature specimens appear to belong to the species which I have been recording 

 under this name. 

 I). Dislomurn appendiculatum Rudolphi. 



Some small slender distomes agree closely with this species. 



7. Distomum nigroflavum Rudolphi. 



Four, 3 adult and 1 young. 



8. Distomum lenue Linton. 



Forty-nine were counted. These agree with those from the common dolphin referred to this 

 species. 



9. Distomum dentatum Linton. 



Two small distomes were found which differ from No. 8 in being flattened dorso-ventrally instead 

 of having a cylindrical shape. They resemble this species, but are devoid of oral spines. 



10. Distomumsp. [See figs. 213, 214.] 



Six: These are the same as No. 12 under the common dolphin. Their most conspicuous character 

 is the very voluminous intestinal rami which obscure the other organs, if any are yet developed, hut 

 which an- themselves translucent. 



PARASITIC COPEPODS. 



11. Lernxonema sp. 



Numerous on dorsal fins and sides; on all, but most abundant on one of the fish; egg-chains 

 variously colored, green and purple; all with heads deeply buried in flesh of host. 



12. Caligus sp. 



( tne; yellow ish-brown.
