EOLIS VIRIDIS, Forbes. 



E. gracilis, viridi-albida ; branchiis linearibus, acutis, viridibus, apicibus albis, seriebus 

 10 subremotis digestis; tentaculis linearibus, lsevibus, tequalibus ; lateribus anterioribus pedis 

 subproductis. 



Montagua vifidis, Forbes, in Ann. Nat. Hist., v. 5, p. 106, pi. 2, f. 18. 



Eolis viridis, For. and Hani., Brit. MolL, v. 3, p. 603, pi. bbb, f. 3. 



Hab. In twenty fathoms water, Isle of Man, and twenty-five fathoms, Cornwall, Professor E. 

 Forbes. Saltcoats, and Portincross, Ayrshire, Rev. D. Landsborough, jun. 



Body three tenths of an inch long, slender, white tinged with yellowish-green. 

 » Dorsal tentacles rather long, linear, smooth, greenish white. Eyes very conspicuous at their 

 posterior base. Oral tentacles linear, about the same length as the dorsal pair, set on the 

 upper surface of the lip ; ends blunt. Branchice nearly linear, rather stout, somewhat 

 abruptly pointed; the central gland of a bright bluish-green, varying to grass-green and 

 bottle-green, and always much and strongly spotted with darker granules ; the sheath is 

 much wider than the gland, and the surface is sprinkled with opaque white spots, most 

 numerous down the front; the apices are opaque white, apparently from the opacity of 

 the ovate vesicle, which is very large, and not, as usual, from a white ring on the 

 surface. The papillae are set in ten rather distant rows, the four anterior rows being a little 

 closer than the rest, and the first approaching to the sides of the dorsal tentacles. The rows 

 contain from four to seven papillae each, diminishing in size as they approach the foot. 

 Foot yellowish white, slightly indented in front, a little produced and obtuse at the sides, 

 tapering to a point behind a little beyond the branchiae. 



Eolis viridis was first obtained by Professor E. Forbes on an Antennularia dredged in 

 deep water off Ballaugh, Isle of Man, and the same distinguished naturalist has since met 

 with it on the coast of Cornwall. We have had it twice sent to us alive by the Rev. David 

 Lansborough, jun., from the Ayrshire coast, where it was found at low-water mark. A 

 specimen, which spawned with us in April, 1847, shows the spawn to be of a flattened form, 

 attached by one of its edges, and forming a coil of nearly two volutions. • The eggs are pale 

 yellow, and are promiscuously scattered through the gelatinous envelope.
