118 Description of New and Little knoivn Species of 



Genus Proctonotus. A. and II. 



Animal oblong, depressed, pointed behind ; dorsal tentacles 

 2, linear simple, with eyes at their base, behind ; oral tentacles 

 short ; head covered by a small semi-lunar veil ; mouth with 

 horny jaws ; gills- papillose, on ridges down the sides of the 

 back and round the head in front ; vent dorsal. — Woodward. 



Pkoctonotus Orientalis. Kel 



Animal semi- gelatinous, greenish. Dorsal tentacles 2, bifur- 

 cated and retractile. Oral tentacles short, pointed. Bran- 

 chiae, 4 or 5 rows on each side of body, those nearest the body 

 smaller ; wedge- shaped, rounded superiorly, flattened ; green, 

 spotted grey and green. Branchiae carried round the head 

 in 2 or 3 rows ; middle ones longer, all of the same shape. 

 Foot broad, long, grooved in foot. Length 2 J inches. Ova 

 white, in waved thread-like coils. 



This exceedingly interesting animal may perhaps occupy 

 a new generic place, as I do not observe the bifurcated dorsal 

 branchics noticed in the other species of the genus Proctonotus. 

 When coiled up it looks like a flower, with green petals. 



Found in Trincomalie, in May and July. 



Pterochilus Viridis. Kel. 



Animal light green. Length \ inch. Tentacles two, simple, 

 long, pointed. Head with small lateral lobes. Branchiae very 

 numerous, closely set; long, linear, acutely pointed. Branchiae 

 green, and spotted with darker green and grey. Foot linear. 

 Found on sea weeds, and, owing to its colour, not easily 

 recognised. Lives for a long time in confinement. Ova 

 green.
