NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 141 



46. L. robusta (Ehlers) (1887, p. 104) off Florida and Havana, in 75- 

 175 fms. (The first parapodia are shown with only limbate setae 

 but other anterior setae were not described; the maxillary formula 

 is 5, 1, 1.) 



47. L. sarsi (Kinberg) (1865, p. 569) from Guayaquil, Ecuador. 

 (This has simple hooks from the first parapodium; the posterior 

 postsetal lobe is long, oblique to erect; the maxillary formula is 5, 

 2,1.) 



48. L. similabris (Treadwell) (1926, p. 5) from Alaska. (The setae 

 have not been described.) 



49. L. singularisetis (Treadwell) (1931, p. 1 ) from Monterey, Cali- 

 fornia. (The distribution of setae remains unknown and proboscid- 

 ial parts are not described.) 



50. L. sphaerocephala (Schmarda), originally described from New 

 Zealand, has been reported from Gorgona Island (Monro, 1933, p. 

 86). (This may include L. obtusa Kinberg, but there are discrep- 

 ancies in accounts. Augener, 1913, p. 288, reports the prostomium 

 as conical, with composite hooks present from the first parapodium; 

 Fauvel, 1932, p. 152, says the prostomium is short, globular.) 



51. L. tenuis (Verrill) (1873, p. 594) off New England. (Simple 

 hooks are present from the seventeenth segment; the maxillary 

 formula is 6-5, 1-1, 1-1 ; parapodial lobes are short throughout.) 



52. L. testudinum (Augener) (1922, p. 46) from Tortugas, Florida. 

 (This is incompletely known.) 



53. L. tetraura (Schmarda), p. 147. 



54. L. virgini (Kinberg) (1865, p. 568) from Patagonia. 



55. L. zonata (Johnson), p. 146. 



The following of the above-named species are believed to belong to 

 Group A, since they lack composite hooks or setae : 



L. acuta (Verrill), p. 145 fL. Candida Treadwell (see also 



L. africana Augener under B)
