DEVANEY 



Research Laboratory (MPRL) (Martin, 1957). As a result, 

 one new species of trematode (fluke) was described from 

 specimens of a butterfly fisfi (Martin and Hammerich, 

 1970). 



Four new species of turbeliarian polyclad flatworms 

 were reported by Hyman (1959) from Enewetak as a 

 result of collections made by D. I. Reish in the summer of 

 1956 from reef flat rocks and algal thalli. An undetermined 

 rhabdocoel was collected from a shell and coconut contain- 

 ing fresh water found on the ground during the summer of 

 1963 (Maguire, 1967). 



NEMERTEA (Ribbon Worms) 



Three species of benthic nemertine worms found at 

 Bikini and Enewetak in 1946 included only 

 one — Baseodiscus delineatus, 30 cm long, 4 to 5 mm 

 wide — from Enewetak (Coe, 1947). This specimen was 

 collected in shallow water on the lagoon side of 

 Bogon, (Boken) Islet. Subsequently, it was noted that nem- 

 crteans made up 25% of the meiobenthos from interstitial 

 sands examined at Enewetak. Two undetermined nemer- 

 teans, collected on the reef flat beachrock near the quarry 

 on Enewetak islet, have been deposited in the MPRL refer- 

 ence collection. 



NEMATODA (Roundworms) 



The distribution and biological relations of a stomach 

 nematode, Protospirura muricola, found in rats and house 



mice at Enewetak were reported by Jackson and Bastian 

 (1975). Undetermined nematodes have been recovered 

 from the gut of a porpoise and from the feces of a large 

 ray collected at Enewetak. No study has yet been made on 

 the free-living nematodes from the atoll's marine or terres- 

 trial environment. 



ACKNOWLEDGMENT 



Appreciation is extended to D. Hope for his sugges- 



tions.
