Maldane sarsi Mgrn. 



This species has ah-eady been recorded by Mcintosh from south of 

 Yedo and by Wirin from the Vega collections in Bering Sea. The 

 "Albatross" examples are of small size and are referred somewhat 

 doubtfully to this species as they differ from the published figm-es 

 and descriptions in several respects. The palpode is much broader 

 with very numerous eyes, the cephalic plate inclined to the longitudinal 

 axis at a very acute angle, the median ridge posteriorly depressed and 

 obscure, the anal plate broader and each dorsal angle of the ventral 

 lobe produced into a distinct spine. There are also some peculiarities 

 of the setse. The anterior end, and especially the head, is generally 

 closely spotted with reddish-brown.

 Maldane coronata sp. nov. (PI. XX VII, figs, w, 95, 96.) 



This is a large species, the type of which measures 130 mm. long by 

 5 mm. in greatest diameter in a contracted state, while fragments 

 of other specimens from the same locality are more than twice as 

 large, so that a length of 300 or 400 mm. in life is not improbable. 



Head acute, cephalic plate narrowly ovate, produced anteriorly into 

 a pointed thin process or palpode, hmbate margin prominent, di\-ided 

 on each side by a lateral cleft which passes into a deep slit on the 

 side of the peristomium ; the posterior half high, erect, its margin 

 coarsely serrate with 15-22 teeth, which are large anteriorly, and pro- 

 gressively diminish in size toward the dorsal mid-hne; anterior half 

 lower, more spreading, passing into the anterior palpode without 

 sharp demarkation, its margin bearing on each side from 4 to 7 (com- 

 monly 5) stiff processes, decreasing in size from behind forward, and 

 the largest about 4- the width of head, often asymmetrical and some- 

 times bifurcated; median ridge moderate, about i cephahc plate, its 

 posterior end about opposite the most anterior marginal process, an- 

 teriorly ending in much broader palpode, rather low and wide but 

 prominent and sharply defined by deep, narrow, sensory grooves, 

 Peristomium short, biannulated by the deep lateral grooves above 

 alluded to, which cut off a small incomplete anterior ring. 



All following preanal somites (19 in number) are setigerous; II to 

 V short and biannulate, the anterior annulus the larger; VI and VII 

 transitional, the others uniannulate and elongated, the last few dimin- 

 ishing somewhat in length, the furrows indistinct. 



Anus dorsal, external to funnel, between this and a prominent 

 integumental fold which covers it. Anal funnel very large, divided 

 by a pair of obUque lateral clefts into dorsal and ventral lobes ; ventral
