identified wiih the above-named variety of Potts, thouo^h its characters are somevvhat deviating 

 from the description of ihat aiithor ; f. i. the elytra kick the large oval chitinous patches, des- 

 cribed and figured by Potis. They are densely covered with papillae, each bearing one, two, 

 three or a real crown of spinelets on their tip, all tinged with red. Among them there is a 

 larger kind of red papillae, spherical in sha]je, not covered over their surface with spines hut 

 with small scales and with a nipple-shaped tip.

Length of the worm about 14 mm., whereas its broadth without bristles is 4^.-, nim. 

 The head is more broad than long, with two large eyes, that lie close to each other on its poste- 

 rior half, partly covered b\' the nuchal collar, that is provided with two lateral papillae. The 

 distal joint of the lateral antennae, twice as long as the head, is provided with a hliform tip ; 

 that of the tentacle is somewhat longer. The palpi are slender, nearly as long as the tentacle. 

 Of the tentacular cirri the dorsal one is the longest. The elytra (PI. XVII, fig. i) are elliptical 

 or faintly reniform without any marginal appendages, with the scar of attachment situated some- 

 what eccentrically ; their uncovered part is beset with a great number of rather large obtuse- 

 conical papillae, already visible by low power, whereas on the covered part there occurs a band 

 of small tubercles. However in an other specimen from the same locality these papillae are 

 entirely absent and on the granular surface only some branching nerve-stems are visible. Both 

 lobes of the parapodia show an elongated appendage, enclosing the acicula ; that of the ventral 

 one is the largest. The n(!uropodial bristles (PI. XVII, fig. 2) have a wedge-shaped, dilated distal 

 end, with taint transverse striae, but without secondary process; the notopodial setae are slightly 

 curved, with taint transverse rows and an obtuse tip. The ventral cirrus does not reach to the 

 distal extremity of the neuropodial lobe; the dorsal cirrus is verv long, e.xtending beyond the 

 end of the neuropodial fascicle. 



This species is easily recognisable bv the conspicuous papillae of its elytra and the 

 feature of its bristles.

A true Lepzdojioh/s-spedes, 18 mm. long and consisting of 27 segments, could not 

 be identified with one of the known species. The head (PI. XVII, fig. 3) is rounded, nearly 

 as long as broad, with the eyes situated close to each other in its posterior half, like in 

 Polymoc crinoidicola Potts -, the anterior ones are the largest and lie .behind the lateral pro- 

 minence. The distal joint of the tentacle is nearly as long as the head, terminating with a 

 filiform tip like all the cirri ; the lateral antennae are only slightly shorter. The palps are smooth,
