describes it, but the mandible is quite different. Ehlers shows the mandible as 

 constricted near the middle of the shaft, which widens at either end. My specimens 

 have a mandible much more like that of L. sphcerocephala as given in Ehlers's plate v, 

 figure 11. This mandible which Ehlers figures is very different from anything which 

 has been described for this genus, and it seems to me legitimate to question whether 

 it was a normal specimen. 



Schmarda recorded the species from Port Jackson; Ehlers from Chatham, Waitangi; 

 Augener from Sharks Bay, 2 to 4.5 meters, Cockburn Sound, Port Royal, 14.5 to 18 

 meters, Albany, Princess Royal Harbor and Oyster Harbor.

Two specimens were collected in Pago Pago Harbor, on the under surface of loose 

 coral rock at Utile reef. This is an unusual position for this genus, which is essentially 

 mud-dwelling. The larger individual is 250 mm. long and composed of about 300 

 somites. The pygidial region is regenerating and contains about 15 very short and 

 narrow somites. There are two pairs of short, stout, unequal anal cirri, v. Maren- 

 zeller's specimen lacked the posterior end. The second of my specimens is only about 

 two-thirds as large as the other one, and only the anterior half is retained. 



The prostomium (plate 7, fig. 1) is about as wide as it is long, with a blunt-pointed 

 apex. The peristomium is a Uttle wider than the prostomium, and is about twice 

 as long as somite 2, from which it is separated bj'' a poorly defined constriction. Ven- 

 trally, as is characteristic of this genus, somite 2 extends forward through an interrup- 

 tion in somite 1 to form the posterior border of the mouth. This ventral prolongation 

 is longitudinally plicated. 



The parapodia have prominent posterior lobes and, as stated by v. Marenzeller, 

 each parapodium has a rudimentary dorsal cirrus into which a tuft of seta extends 

 (plate 7, fig. 2, taken from somite 100). Posteriorly there is an increase in the length 

 of the posterior parapodial lobes, but aside from this the parapodia are of the same 

 form throughout. 



The maxilla (plate 7, fig. 3) is dark brown, almost black, but with occasional lighter 

 brown areas, especially along the margins of the carriers. The carrier is rather long 

 and the margins have a frayed appearance. The forceps is slender. The left 

 proximal plate has 4 teeth, the right proximal has 5. Apparently the 2 terminal teeth 

 of the right plate are more or less broken. The second and third pairs of plates have 

 respectively 2 teeth and 1 tooth on a side. In the figure these are shown as inverted, 

 a position assumed during dissection. The teeth should lie on the inner side of each 

 plate. The mandible (plate 7, fig. 4) is narrow at the base, but broadens at the anterior 

 end. It is marked by concentric lines both in the shaft and in the beveled portion, 

 the latter with very darkly pigmented ends. 



v. Marenzeller gives no drawing of the prostomium, but his figures of parapodia 

 and jaw agree so well with those of the Samoan specimens that I have no hesitation 

 in assigning them to this species, v. Marenzeller figures three forms of seta^, simple 

 winged, simple hooded, and compound hooded, the last two agreeing in form of apex 

 and hood. In the smaller of my two specimens I find the form and distribution of 

 setae exactly as v. Marenzeller described them, but the larger specimen lacks the 

 compound ones. It would be desirable to examine a series of varying sizes to determine 

 if these setae are lost with increasing age or size, but the material now in hand is not 

 sufficient for this purpose. 



Moore (1903, p. 454) records this species from Sagami and Suruga Bays, Japan, 

 v. Marenzeller's was from the east coast of Eno-Sima Island.
