342 ON A COLLECTION OF ECHIURIDS, WITH AN ATTEMPT TO 



Length of body some 15 cm.; of proboscis, when full}* extended. 150 cms. 



Colour, dark green, almost black green, the ventral middle line is lighter. 



Papillae appear as dark, scattered spots, all over the body. 



Longitudinal muscles continuous. 



Nephridium single, usually that of the right side. 



Anal trees, short and sac-like with diverticula which branch twice before ending 

 in funnels. 



Sexes unlike. Male small and parasitic in female, with no hooks, uniformly ciliated 

 and not anuulated. Larva with no ventral sucker. 



Locality. Mediterranean, Adriatic ; Port Jackson, Australia ; at Dyveholmen on the 

 West coast of Norway ; Trondhjem Fjord, Bergens Fjord, and Kors Fjord. In the last- 

 named two places the animal was dredged at a depth of 50 — 100 faths., on a sandy 

 bottom. Besides the Loyalty Islands where Dr Willey's specimen was taken, this species 

 was seen by him in the D'Entrecasteaux Group, British New Guinea. 



Genus II. ECHIURUS. Guerin-Meneville 1 . 



The generic name Echiwrus seems to have been first used by Guerin-Meneville for 

 Pallas' genus Lumbncus echiurus. Cuvier had previously used the word " echiures " but 

 not in a generic sense. Guerin-Meneville attempts no description of the genus, but he 

 names it and gives a satisfactory figure of Echiurus pallasii. The date on the title- 

 page is 1829 — 1843, but Mr Davies Sherborn has been kind enough to tell me that the 

 plate dealing with Echiurus was not published by January 1831, although the name 

 was in full use in 1835 s . Guerin-Meneville's text was published as a whole in 

 September 1844.

 Synonym. E. farcimen, Baird. J. Linn. Soc. Vol. xi. 1873, p. 97.

 bigger, the largest attaining a length of 16 ins. 



Length of body variously given as 6*5 ins., 14 cm., 16 ins. Diameter of body 3 cm. 

 Length of proboscis 6 — 7 mm. 



Colour, faint yellowish grey. 



Papillae almost uniformly distributed over the body, and except at the hinder end, 

 very close together. A single ring of 11 bristles.
