very closely with LicJiOfiioloi>iis, but differ very much from that 

 genus in the structure of the second maxillipedes. In Licho- 

 nioloi^iis this pair of maxillipedes in the female are stout, and 

 terminate in an almost obsolete tooth-like claw. Indeed, he 

 (Dr. Scott) does not remember any described genus to which 

 these specimens can be satisfactorily ascribed. If the specimen 

 dissected had been a male mstead of a female it would have 

 agreed fairly well with Lichoniologtis, as the male in that genus 

 has the second maxillipedes usually furnished with a moderately 

 long claw, but as it is a female it exhibits in its appendages a 

 relationship to both Lichoiiiologiis and Stihc'llipliiliis.

The species is large, attaining (in spirit) a length of 100 mm., 

 and a breadth between the bases of the anterior bristles of. 14 

 mm. Of the total length, about 18 mm. pertain to the 

 branchiae, 27 mm. to the anterior (thoracic) region, and 55 mm. 

 to the posterior region. 



The dorsal surface is grooved along the middle line 

 anteriorly, but is convex posteriorly. The ventral surface, on 

 the other hand, is deeply grooved throughout, the groove, how- 

 ever, being interrupted by the deep membranous apron at the 

 posterior part of the thoracic region. 



At the truncated anterior end the mouth opens dorsally as a 

 deep pit with a smooth papilla projecting out of it. Similar 

 grooves to those in Bispiirh lead from the spirals of the 

 branchiae to the mouth, and probably subserve the same pur- 

 pose, viz., the conveyance of food and mucus. 



The branchiae form two dense masses on each side, attached 

 by a surface shaped somewhat like a trefoil to the bodv. More- 

 over, the left mass is composed of three spirals which are 

 mounted on a basal region composed of a single spiral. Such 

 may be an abnormality. 



The right side has but a single complex spire considerably 

 longer than the compound one on the left, the last whorl 

 terminating dorsally and sending from its edge a lamina 

 towards the mouth, apparently for directing currents thereto. 



The filaments have a dense series of somewhat short pinnae 

 which proceed to the tip, the latter only being distinguished by
