144 MESSRS. ALDER AND HANCOCK ON 



EOLIS MILITARIS, D. Sp. (PI. XXXIII. fig. 15.) 



Body rather stout, tapering to a fine point behind, of a pale flesh-colour or nearly 

 -white. Dorsal tentacles rather long, smooth, swelling a little in the centre, and tapering 

 to a point above, with a broad belt of scarlet near the centre, gradually fading into flesh- 

 colour below ; bright yellow on the upper half, excepting the extreme tips, which are 

 white. Oral tentacles large, stout, and tapering, coloured as the dorsal, excepting that 

 the scarlet central belt is extended down each tentacle in a narrow line, the two uniting 

 in a bulb on the centre of the head, and continued thence backwards to the com- 

 mencement of the branchial papillae : a scarlet line also runs along each side of the 

 body from the anterior angles of the foot. Branchial papillae numerous, moderately 

 stout, of a reddish-brown colour, with bright yellow tips, forming six clusters on each 

 side, and nearly meeting on the back. Foot with the anterior angles much produced 

 and stout, terminating behind in a slender tail considerably behind the branchiae. 

 Length 1 inch. 



Tongue with a single series of fifteen or sixteen denticulated spines : there are seven 

 denticles on each side. The jaws are broad, with the cutting edge denticulated. 



This handsome species bears considerable resemblance to the last in colour and mark- 

 ings ; but diff'ers in the absence of rings on the dorsal tentacles, and in the produced 

 anterior angles of the foot. The colours are also more brilliant. The remains of a 

 single specimen only were in the collection. 



EOLIS OCELLATA, U. Sp. (PI. XXXIII. figS. 16, 17.) 



Body linear, white, spotted and blotched with yellow. Dorsal tentacles long and 

 slender, smooth, tapering to a fine point; yellowish brown in the centre, and white 

 above and below, with a few yellowish spots near the base. Oral tentacles about half 

 the length of the dorsal pair, white, confluent with the line of the head. Branchial 

 papillae rather inflated for about two-thirds up, where they become suddenly contracted, 

 and linear towards the apex, which is encircled with brown ; five or six brown rings 

 form a chain-like circle round the upper part of the inflated portion, the rest of the 

 surface is white, spotted with yellow, and there is a narrow brown central gland : the 

 papillae are set in four clusters, the front ones much the largest. Foot with the angles 

 produced into long tentacular processes in front, rather broad and fin-like towards the 

 tail. Length about f ths of an inch. 



The spawn forms a narrow white riband, loosely coiled in one or two volutions. 



This species is rare. No specimen was preserved.
