Order Lucernaricc. 541 



tween this species and the last, is that this has an exceed- 

 ingly short pedicel, consisting merely of a very broad 

 disciform base which is attached to the bell by a deep 

 constriction ; the tentacles are also said to be short, but 

 this is rather a vague term, especially as the figures repre- 

 sent them as long as in some other species of Lucernariie 

 in which they can only be called long. The color is so 

 variable among these animals that it cannot be used as a 

 mark of distinction. Size, about an inch in height. Ge- 

 ographical distribution : Berwick Bay, east coast of Scot- 

 land, Johnston ; Tor Bay, south coast of England. May, 

 1833, Coldstream. 



Manania.* H. James-Clark. 



Disc urnaeform, octohedral ; the arms produced : pedicel 

 monocamerous ; the camera simple : tentacles in groups 

 at the end of the arms, but a little within the muscular 

 margin of the bell ; outer or distal row pistilliform ; the 

 radial diameter of the groups greater than the transverse : 

 marginal anchors pistilliform, situated just within the 

 muscular margin: genitals transversely folded, terminating 

 at a greater or less distance from the margin of the bell ; the 

 digitiform bodies accompany the united bands across the 

 proximal end of the partitions : muscles of the pedicel 

 four, equidistant, imbedded in the gelatiniform layer: prin- 

 cipal muscles of the disc ligulate ; from each side of the 

 proximal end of a partition one extends in a direct line to 



British Zoijphytes the description is modified so as to correspond with the L. 

 campanulata, Lamx, with which be mistakenly identifies the originals. Curiously 

 enough too, L. campanulata, Lamx, belongs not only to a different genus, but also 

 to a diflferent family from the L. convolvulus. 



* As in the case of Calvadosia and Haliclystus salpinx, I am indebted to Mr. 

 Stimpson for specimens of this genus, which he collected near the island of Grand 

 Manan, off Eastport, Maine. Unfortunately he made no written notes upon it while 

 it was in a living state, but he tells me that he identified it at the time with the 

 Lucernaria auricula, Fabricius, as described by that author in his Fauna Gron- 

 landica; and this is the same conclusion I have come to independently.
