African species is from Simon's Hay, eastward to the Tugela River, 

 Natal, while the preceding species seems to range rather from 

 Simon's Bay westward and northward. This apparent difference of 

 distribution may however be quite unreal and due only to our present 



ignorance.

MARIAMETRIDAE. 



LlPAROMETRA MULTICIRRA, * Sp. nOV. 



Plate VIII. Fig. 2. 



Disk about 23 mm. across, ver^ deeply incised; arms about 85 

 mm. long but they are not quite equal and some scarcely exceed 

 75 mm. Disk membrane full of crowded, small, calcareous plates. 

 Centro-dorsal large, thick, dorsally flat or a little concave, 6 mm. 

 in diameter; bare dorsal area, nearly 4 mm. across. Cirri XLIII, 

 30-36, cylindrical at base, but compressed distally; the segments 

 710 have the length about equal to or even a little exceeding the 

 diameter, but elsewhere the greatest diameter exceeds the length ; 

 beginning usually with the tenth or eleventh segment, but on some 

 cirri further out, there is a median, dorsal elevation, at first rather 

 blunt but soon with a short compressed tip or even a sharp point; 

 on the last segment this becomes an opposing claw as long as half 

 the diameter of the segment ; terminal claw longer than last segment, 

 very sharp. 



Arms about 50, all but two broken and detached from disk at or 

 near base; arm-segments numerous, exceeding 150, the distal ones 

 being quite short. Division series all 2, well-separated, rounded and 

 smooth. First syzygy between brachials 3 and 4 of the free arm ; 

 second syzygy far out, usually after an interval of more than 20 

 segments and often 30-40, rarely before segment 20; subsequent 

 syzygies few and at very wide intervals. Low and relatively incon- 

 spicuous synarthrial tubercles occur on all the division series. 



Lower pinnules not noticeably larger on outer side of arm than 

 on inner. P, (P,, similar) about 9-10 mm. long, consisting of 17-21 

 segments, all but the basal three longer than wide and all but the 

 basal five or six, cylindrical. P. 2 and P/, very similar but noticeably 

 larger, 12-13 mm. long, with 24-26 segments. P 3 and P t similar 

 to P 2 and approximately equal, or a little smaller and with 1-3 

 fewer segments. P/, and P ( < distinctly smaller, about equal to Pj. 



* Multicirrus = having many cirri.
