TYPES OF POLYCHAETE WOKMS HARTMAN 123 



Genus ADMETELLA Mcintosh 



ADMETELLA RENOTUBULATA (Moore), new combination 



Polyno'e (?) renotubulata Moore, 1910, p. 368 (U.S.N.M. no. 16878, Calif oruia ) . 



Moore has already indicated the relation of this species with those 

 of the genus Admetella. The type is notably smaller than those of 

 two other species in the collections of the Museum, A. dolichopus and 

 A. hastigerens Chamberlin. Also, it has only 35 segments and 14 

 pairs of scales as against the 60-75 segments and 23-30 pairs of scales 

 usually present. Moore's type may possibly represent an immature 

 specimen. 



Genus Indeterminable 



Polynoe {?) fllamentosa Moore (1910, p. 366, U.S.N.M. no. 17221), 

 from California, is unique in its parapodial structures. The noto- 

 podium is well developed; notopodial setae are pale amber, heavier 

 than the neuropodials and some quite as long. Neuropodial setae are 

 flat, thin, transparent, somewhat resembling those in MacelUcephala. 

 The prostomium is more than twice as broad as long, and apparently 

 without eyes. The median ceratophore is stout, produced between 

 the prostomial lobes and extends distally to the ends of tlie tiny 

 papillalike prostomial peaks. The single type is fragmentary and 

 does not permit a complete description. 



Polynoe innatam Chamberlin (1919a, p. 70, U.S.N.M. no. 19459), 

 from near the Galapagos Islands, is perhaps a species of Eucranta 

 Malmgren. It is tiny, only 9.5 mm long, translucent, and without indi- 

 cation of sexual products; thus it may be an innnature pelagic stage. 

 The tyj^e resembles Euoranta as defined by Monro (1936, p. 100) in 

 that (1) the notopodial setae are stouter than the neuropodials, (2) 

 the neurosetae are of two kinds, both bidentate distally, and (3) the 

 superior neuropodial setae are long, slender, pectinated, the inferior 

 are stouter, shorter. The prostomium is harmothoid. Tliere are only 

 26 setigerous segments and 11 (or possibly 12) elytrophores. 



Family POLYODONTIDAE 

 Genus EUPANTHALIS Mcintosh 



EUPANTHALIS MUTILATA (Treadwell), new combination 



FiGUEEs 40, a-f 



Polynoe mutilata Treadwell, 1906, p. 1152 (U.S.N.M. no. 5204, Hawaiian Islands). 

 ': Eupanthalis oahuensis Treadwell, 1906, p. 1155 (Hawaiian Islands). 



I have not seen the type of Eupanthalis oahuensis. There is no 

 record of the deposition of this type in the National collections. 



The following description is based on the type of P. mutilata. The 

 specimen consists of head and 78 segments, in two pieces. The head
