SG2 NOTES ON SOME r.lJTTISlI XITDIBRANCHS. 



l)osterior jiart of the body had been lost, as it ends abru})tly only 3-4 mm. 

 behind tiie heart.* Tlie outline of the anterior end of the foot is like 

 Eolis nana, except that the sides are produced into small angular pro- 

 jections kept tucked in and consecpiently inconspicuous. Head nearly 

 as wide as the foot. The oral tentacles very minute; merely short pro- 

 cesses of angles of the oral veil. The rhinophores are long and smooth, 

 held erect with tips bent back. The eyes do not show. Papillie very 

 numerous and extremely long, slender and tapering to fine points, con- 

 stantly in motion, curling and uncurling, and when at rest convoluted. 

 A group of small papillae, api)arently three rows, is wholly in front of 

 the rhinophores on each side. Then a row on each side al)reast of 

 rliinophores. Another row between this and the next, which is abreast 

 of the anterior end of the heart. Then a row level with the posterior 

 end of the heart. The outer ends of the rows are not double. 



" The colour of the body is red, tending to orange on the rhinophores, 

 but elsewhere more rosy. The colour seems to be situate in the super- 

 ficial tissues. The papillae are superficially fiesh-coloured. The hepatic 

 ccBca are in most of the papilhe rosy purple throughout, but in a few 

 pale greenish purple, except at the ti}), wiiich is rosy purple in all and 

 more deeply coloured than the rest of the organ. The cceca are slender, 

 especially at the distal ends, and much corrugated. The extreme tips 

 of the papilUe beyond the end of the coeca are yellowish flesh colour, 

 deeper than the superficial colour of the rest of the papillie." 



I have examined two preserved specimens given me by Mr. Beaumont, 

 20 mm. and 14 mm. long respectively. The colour is dead white, not 

 very transparent. The hepatic diverticula are yellowish white and 

 corrugated. The external characters agree with Mr. Beaumont's 

 description. The front of the foot is broad and expanded, but the 

 tentacular angles are small and bent downwards and inwards. The 

 anterior margin is not grooved. Over the mouth is a l)road oral veil 

 (5'3 mm.) expanded into short tentacles (T? mm.) at the sides The 

 rhinophores are long (7'5 mm.), thin, not perfoliate, and placed close 

 togetlier on a slight prominence. There are three rows of cerata 

 distinctly in front of them. The cerata are set on eight narrow, curved 

 ridt'es, which are sinfjle and do not form horseshoes. The first three 

 rows are close together, the next three not far apart, but tlie last two 

 are more distant. In the perfect specimens the length of the cerata 

 obscures this arrangement. There are four to six cerata in each row. 

 The cerata in front of the rhinophores are short, cylindrical, and 

 2-4 nnii. long. The posterior cerata are very long; in the specimen, 

 which has a body 20 mm. loiig, they measure as much as 15 mm. and 

 are about 1 mm. broad at the base.
