126 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 10 



Genus MARPHYSA Quatrefages 

 Type M. sanguinea (Montagu) 



This genus is most clearly separable from Eunice (above) for lack- 

 ing peristomial cirri. It has been recorded from the Americas through 26 

 species (excluding synonyms), but many are so poorly known that their 

 status continues to be doubtful. They include : 



1. Al. aenea (Blanchard), p. 128. 



2. M. antipathum Pourtales (1869, p. 109) off Havana, in 270 fms. 

 (This is known only through a brief description, based on a tube.) 



3. M. aransensis Treadwell (1939, p. 5, figs. 16, 17) from Texas. 

 (This is not distinguishable from M. sanguinea, below.) 



4. M. atlantica (Kinberg) (1865, p. 565) off the La Plata River, 

 Argentina. 



5. M. bellii Audouin and Edwards, originally described from Europe, 

 reported from Florida (Ehlers, 1887, p. 95). 



6. M. bellii oculata Treadwell (1921, p. 61) from the West Indies. 



7. M.. brasiliensis (Hansen) (1882, p. 7) from Brazil. (This has been 

 regarded as a probable synonym of M. sanguinea by Augener, 1934, 

 p. 136.) 



8. M. brevitentaculata Treadwell (1921, p. 69) from the West Indies. 

 (This is not distinguishable from AI. sanguinea, below.) 



9. M. conferta Moore, p. 129. 



10. M. gayi Quatrefages (1865, p. 335) from Chile. 



11. M. hamata (Schmarda) (1861, p. 125) from Jamaica. 



12. AI. hentscheli Augener (1931, p. 44) from Jamaica. 



13. AI. januarii Grube (1881, p. Ill) from Rio de Janeiro, Brazil. 



14. AI. languida Treadwell (1921, p. 73) from Puerto Rico. 



15. AI. minima (Hansen) (1882, p. 8) from Rio de Janeiro, Brazil. 



16. AI. mortenseni Monro, p. 129. 



17. AI. nobilis Treadwell (1917, p. 265) from Florida. (This appears 

 to be the same as AI. sanguinea, below.) 



18. AI. qiiadrioculata (Grube) (1856, p. 60) from Puntarenas, Costa 

 Rica. (This is very incompletely known.) 



19. AI. regalis Verrill (1900, p. 56) from Bermuda, later described as 

 AI. fragilis Treadwell (1911, p. 2) from Florida. 



20. Ad. sanguinea (Montagu), p. 127. 



21. AI. sanguinea americana Monro ( 1933, p. 68) from Balboa, Panama. 



22. AI. schmardai Gravier (1909, p. 634) from Peru. 



23. AI. simplex Crossland, first described from Zanzibar, reported from 

 French Guiana by Fauvel (1919, p. 476).
