138 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 10 



3. L. acuta (Verrill), p. 145. 



4. L. africana Augener, first described from west Africa, is reported 

 from the Galapagos Islands (Monro, 1933, p. 86). 



5. L. atlantica Kinberg (1865, p. 568) from the La Plata region, 

 Argentina. (This is provided with only limbate setae in 13 anterior 

 segments, but thereafter has simple, hooded hooks, as I was able to 

 confirm through re-examination of the type specimen at Stockholm.) 



6. L. bicirrata (Treadwell), p. 156. 



7. L. bidens Ehlers (1887, p. 103) off Florida, in 339 fms. 



8. L. bifilaris (Ehlers), p. 153. 



9. L. bifrons (Kinberg) (1865, p. 567) from Cape Virginis, Pata- 

 gonia. (This was originally described as Eranno bifrons, erroneous- 

 ly referred to a newly erected genus, since the everted nuchal or- 

 gans were interpreted as prostomial antennae. Through the courtesy 

 of Professor Sixten Bock, of the Swedish State Museum, I have 

 seen the type and found it to be a typical Lionbrineris. It is a valid 

 species. Details are discussed in another report, in manuscript.) 



10. L. bifurcata Mcintosh, first described from Japan, has been re- 

 ported from the northeast Pacific (Treadwell, 1914, p. 196; Berke- 

 ley, 1927, p. 409). 



11. L. bilabiata Treadwell (1902, p. 199) from Puerto Rico. (See 

 Hartman, 1942, p. 120.) 



12. L. branchiata Treadwell (1921, p. 94) from Tobago, West Indies. 



13. L. brasiliensis Grube (1856, p. 159) from Rio de Janeiro, Brazil. 

 (This is very incompletely known.) 



14. L. brevicirra (Schmarda), originally described from Australia, has 

 been reported from Coiba Island, Panama, and the Galapagos Is- 

 lands (Monro, 1933, p. 83). However, the latter are believed to 

 belong to L. tetraura, p. 147. Augener (1913, pp. 288-290) rede- 

 scribed the type of L. brevicirra, noted the prostomium to be usually 

 as long as the first 3 segments, reported simple hooks present from 

 the first setiger and simple hooks in posterior segments, the latter 

 with one larger, and 4 or 5 smaller teeth; the maxillary formula 

 was given as 5-5, 2-2, 1-1 ; color of acicula was not disclosed. On 

 the contrary, in specimens from the eastern Pacific, the prostomium 

 was described (Monro, 1933) as short but never globular; simple 

 hooks present from the first setiger; limbate setae present to per- 

 haps the seventieth segment but usually ceasing at about the forti- 

 eth, and jaws as in L. impatiens Claparede. The records of L. brevi- 

 cirra from the Western Hemisphere are not convincing.
