NO. 5 hartman: polychaetous annelids 327 



If we separate these on the character suggested above — uncini with 

 teeth in single series (Cistenides), or teeth in several series (Pectinaria) 

 — the separation differs sh'ghtly. The following 4 species go to Cistenides. 

 (The American species, preceded by an asterisk, are distinguished in the 

 key on p. 330.) 



*C. ehlersi Hessle, from Patagonia, 



*C gouldii Verrill, from eastern North America, south to the West 



Indies, 

 *C. granulata (Linnaeus), from Arctic and North Atlantic oceans, 

 *C. hyperborea (Malmgren), from Arctic, North Atlantic, and 

 North Pacific oceans. 

 The following 9 species go to Pectinaria: 

 P. aegyptia (Savigny), from the Red Sea, 

 P. antipoda Schmarda, from New Zealand and Australia, 

 P. australis Ehlers, from New Zealand, 

 P. belgica (Pallas), from western Europe, 

 P. brevispinis Grube, from the Philippines, 

 *P. chilensis (Nilsson), from Chile, p. 333, 

 P. clava Grube, from the Philippines, 

 P. conchilega Grube, from the Philippines, and 

 P. parvibranchis Grube, from the Philippines. 

 To these, discussed by Nilsson (1928), may be added 3 others in Cisteni- 

 des and 2 in Pectinaria : 



*C. brevicoma Johnson ( 1901, p. 243), from Alaska south to Cali- 

 fornia, p. 331, 

 *C. regalis Verrill (1902, p. 38), from Bermuda, p. 332, 

 C soldatovi Annenkova (1929, p. 486), from north Japan and 

 northeast Asia, bringing the total of Cistenides to 7 species; 

 and 

 *P. calif orniensis, new species, from southern California, p. 333, 

 *P. calif orniensis newportensis, new subspecies, from Newport Bay, 

 p. 335, 

 bringing the total of Pectinaria to 11 species. Two others, P. capensis 

 (Pallas) from southern Africa and P. panava Willey (1905, p. 295) 

 from Ceylon seas, are incompletely known. 



The following chart shows the distribution of some of the more diag-
