anterior end, the posterior of which is only shghtlj^ smaller 

 than the other. There are no marginal denticulations. 11. 

 has the ordinary form of a broad plate with five teeth. 111. 

 is short, with three teeth, the j^i'oximal being small. IV. is 

 bidentate ; and V. has but a single tooth. 



The fifth plate is so closely placed against the fourth that 

 on a first inspection they seemed part of a single plate. 



The lower jaws are kmg and anteriorly broad ; they lie 

 wholly in front of the support of the ujiper jawlets, and each 

 is divisible lengthwise into two aj^proximately equal regions ; 

 the outer region is bi\)Avn, the inner white, being calcified 

 and marked by fine longitudinal lines. 



Remarks. — This species difi'ers from the only other species, 

 L. brasiliensis, Kinbergi in the following features : in the 

 number of teeth on the jaw plates, in the dimensions of the 

 dorsal cirrus and posterior lip, both of A\'hich are narrower 

 than in the present species. Ehlers,2 who figures this species, 

 says that the worm is whitish-grey. 



Loc. — South by south-west of Mt. Cann, Victoria, 55-70 

 fathoms.
