region of somite 50. The prostomium is broader than tlie peristomium (plate 1, 

 fig. 8) and decidedly 2-lobed, its dorsal surface dark in color, the anterior margin and 

 regions lateral to the eyes being colorless. The tentacles are colorless, the median 

 one 4 to 5 times as long as the prostomium and pointed at the apex. The tentacles 

 are more sharply pointed and have longer cirrophores than in L. viridis. 



Preserved material retains the coloration of 

 the anterior end, so that for about the first 40 

 somites both dorsal and ventral surfaces are 

 dark brown. The anterior somites do not have 

 the colorless band on their anterior borders which 

 are present in L. viridis (compare fig. 1 and fig. 

 8, plate 1). The parapodia are uncolored, as are 

 the nuchal cirri. In the epitokous portion there 

 is on either side of the dorsal surface in each 

 somite a dark spot at the base of the parapodium 

 (plate l,fig. 11). Apparently these spots do not 

 extend to the very posterior end, but I could 

 not determine this with certainty in the material 

 at my disposal. They may also be found on a few 

 of the posterior atokous somites. 



A parapodium from setigerous somite 10 is 

 shown in plate 1, fig. 10. The prominent pad-like 

 swelling which carries the ventral cirrus begins at 

 about this region and extends for about the first 

 quarter of the length of the animal. The gills 

 have about the same arrangement that they have 

 in L. viridis, but are more slender, extend into the 

 epitokous region, and are relatively more promi- 

 nent. A small L. viridis may be distinguished 

 from one of the variety of the same size by the 

 fact that the gills in viridis would be much smaller 

 than in the variety. 



An epitokous parapodium (plate 1, fig. 11) has 

 a small dorsal cirrus with the long gill attached 

 near its base. There are two pairs of anal cirri 



quite similar to those of L. viridis, the jaws, except for size, are exactly like those of 

 the species, and the setae and aciculse are similar to those of the species. 



The type is in the American Museum of Natural History.

References to a considerable literature concerning this species and a related or 

 more probably identical form L. kinbergii wdll be found in the works cited above. 

 As the material at my disposal did not enable me to attempt this question of the 

 synonymy, it does not seem necessary to undertake any discussion of the subject. 



Two specimens were collected at Pago Pago, Samoa, the smaller one 220 mm. long, 

 with a prostomial width of 6 mm. and a larger one 450 mm. long, for the part which 

 was preserved, a considerable portion of the posterior end having been lost. The 

 prostomial width is 8 mm.
