pallii margine citrino ; rliinoplioria et branchia rubra punctulis nigris. 
Habitat. — Philippine Sea (Burias, Masinloc), Pacific (Port Denison, Torres Strait). 
Of this species three examples were taken on September 8, 1874, in Torres Strait, 
Station 186, lat. 10° 30' S., long. 142° 18' E. ; depth, 8 fathoms; bottom, coral sand. 
They were well preserved in alcohol. The length reached to between 2 and 3 cm., 
the breadth 11 or 13 mm., and the height 7 to 8 '5 mm.; the breadth of the foot 
3 ‘5-5 mm., the breadth of the margin of the mantle 2-2 ’5 mm. ; the height of the 
rhinophoria 2 '5 mm., of the branchia 3 '5 mm. 
The colour of the animal, preserved in spirit, is black or velvet black ; on the 
dorsal surface of the mantle edge are a number of yellowish-white lines running 
parallel with it, variable in size and in number ; in front the number is somewhat 
smaller than behind, where it is mostly from about six to eight. The dorsal surface 
proper is traversed by a number of similar lines, which are more or less continuous, 
and branch and anastomose ; the margins of the mantle and of the foot are yellowish- 
white in colour ; the under surface of the mantle edge, and the sides of the body as 
far as the margin of the foot, are covered with similar but stronger (8-14) lines, a variable 
number of which are prolonged onwards over the tail. The margin of the rhinophorial 
aperture is whitish ; the stem of the rhinophoria blackish-grey, the club yellowish, with 
white points on the edges of its leaves. The margin of the branchial cavity is sur- 
rounded by radially arranged white lines ; the branchial leaves at the root and along 
the chief rhachis are entirely of a blackish-grey colour, but the leaves themselves are 
yellowish, sprinkled with whitish-yellow points. The anal papilla (and its neighbourhood) 
are spotted with black, whitish at the end ; the sole of the foot is yellowish, the tentacles 
white, the neighbourhood of the mouth yellowish-grey. The genital papilla is whitish. 
The form of the body is as usual. The club of the rhinophoria has from thirty to 
twenty-five leaves. The diameter of the roundish branchial cleft about 4 mm. ; the 
branchia is rolled into a spiral at both ends ; each half is formed of nine leaves, of which 
the five hindermost are smaller and simply feathered, the others are larger and are divided
