99) ; without additional information, however, the older name, P. 

 caudata, remains a questionable synonym. Ehlers (loc. cit.) was unable 

 to distinguish it from either F. lapidosa Kinberg or P. moerchi Kinberg, 

 but the latter is a distinct species (see below). 



Species of the genus Phragmatopoma are not numerous. Most of them 

 originate from intertidal zones of the eastern Pacific and West Indian 

 waters, but they are most conspicuous from western South America. 

 Only one species, P. calif ornica (Fewkes), is known from the northeast 

 Pacific. P. moerchi Kinberg is shown from the Hawaiian Islands and 

 Chile; P. lapidosa Kinberg occurs on both sides of South America, 

 through the West Indian region to southern Florida; P. virgini Kin- 

 berg is from southernmost South America. In addition, 2 species from 

 western South America are newly described below. Sabellaria castelnaui 

 Grube (1870, p. 69), from New Zealand, was redescribed by Augener 

 (1926, pp. 214-215) after re-examination of the original; Johansson 

 (1927, p. 99) referred it to P. lapidosa Kinberg. Sabellaria antipoda 

 Augener, from New Zealand, was referred to Phragmatopoma by Monro 

 (1936, pp. 170-171), but its opercular paleae are unquestionably those of 

 a Sabellaria. One other name merits consideration, since it differs from 

 others named above; it was reported as Sabellaria (Phragmatopoma) 

 virgini Monro (1933, pp. 1062-1063) from Perlas Islands, Panama, but 

 differs from P. virgini Kinberg (below) and other known species of the 

 genus in its outer opercular paleae; I am referring it to P. attenuata 

 (below). 



Phragmatopoma is herein considered to include the following species; 

 2 are described as new. 



1. P. calif ornica (Fewkes) 



2. ?P. caudata (Kroyer) Morch, questionably P. lapidosa 



3. P. lapidosa Kinberg 



4. P. moerchi Kinberg 



5. P. virgini Kinberg 



6. P. attenuata, new species 



7. P. peruensis, new species
