140 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.10 



31. L. janeirensis (Augener) (1934, p. 138) from Rio de Janeiro, 

 Brazil. (This name was proposed to replace Arabella dubia Han- 

 sen, for a form unique in lacking hooded hooks, its parapodia pro- 

 vided with only simple limbate setae.) 



32. L. januarii (Grube), p. 167. 



33. L. latreilli Audouin and Edwards, p. 158. 



34. L. latreilli japonica Marenzeller, p. 159. 



35. L. maculata (Treadwell) (1902, p. 198) from Puerto Rico. (See 

 Hartman, 1942, pp. 119-120.) 



36. L. magalhaensis (Kinberg) (1865, p. 568) from the Strait of Ma- 

 gellan. (Composite hooks are present from the first parapodium; 

 parapodial lobes are short, but the postsetal one is the longer.) 



37. L. moorei Hartman (1942, p. 116) from Catalina Island, in 1,350- 

 2,182 fms. 



38. L. nasuta (Verrill) (1900, p. 651) from Bermuda. (The original 

 description is inadequate; the type is not known to exist. As rede- 

 scribed by Treadwell, 1921, p. 101, it appears to be the same as 

 L. latreilli, p. 158.) 



39. L. nuchalis (Treadwell) (1921, p. 104) from the West Indies. 

 (This has composite setae; the maxillary formula is 5, 2, 1.) 



40. L. obtusa Kinberg (1865, p. 569) from Valparaiso, Chile. (This 

 may prove to be identical with L. sphaerocephala, below. Composite 

 setae are present from the first parapodium; the posterior postsetal 

 lobe is long, directed obliquely upward; the maxillary formula of 

 plates II and III is 5, 2.) 



41. L. oceanica (Kinberg) (1865, p. 570) from the La Plata region, 

 Argentina. (Simple hooks are present from at least the second para- 

 podium; the posterior postsetal lobe is long, equal in length to the 

 parapodial base, and directed obliquely upward.) 



42. L. parvapedata (Treadwell) (1902, p. 198) from Culebra, Pana- 

 ma. (See Hartman, 1942, pp. 118-119.) 



43. L. paucidentata (Treadwell) (1921, p. 99) from Tortugas, Flori- 

 da. (In all respects save one, this resembles L. Candida, above; it is, 

 however, said to have composite hooks from the first parapodium.) 



44. L. punctata (Mcintosh) (1885, p. 252) from off New York, in 

 1,240 fms. (This is an abyssal form, characterized by its long, 

 slender, limbate setae.) 



45. L. quinquedentata (Kinberg) (1865, p. 569) from the La Plata 

 region, Argentina. (This is very incompletely known.)
