Alcyonaria G 29 



As originally established, with its designated type, it is identical with 

 Capnella Kukenthal, * who described my species as C. rugosa. 



Capnella has been made to include several other Indo-Pacific species, 

 rhich should be referred to Eunephthya. Among these are E. spicata (May) 

 >m Zanzibar; E. gilchristi (Thomson) South Africa, 40 fathoms; E. fungiformis. 

 1. thyrsoidea Verrill, was from 20 fathoms, off False bay, Cape of Good Hope. 



Unfortunately Kukenthal applied the name Eunephthya to the second 

 >ecies mentioned by me, and then extended it to include numerous other 

 Arctic species belonging to the genera Gersemia Mar., Duva and Drifa Danielssen, 



My E. glomerata, before KukenthaFs " emendation," had already been 

 placed in two new genera by Danielssen, viz., Drifa and Gersemiopsis. Thus 

 jven if E. thyrsoidea had not been named by me as the type, it would have 

 >ecome so automatically by reason of the placing of E. glomerata in a new 

 genus by Danielssen, in 1887, long before Capnella was expanded. 



Paraspongodes 2 has been used for these various northern forms by May 

 (1898), and by others. It is a heterogenous group, practically a synonym of 

 Eunethphya Kukenthal, in its extended use, and preceded by eight generic names 

 given by Danielssen and others, and therefore it should be dropped for all of 

 our northern genera. Kukenthal described and figured a new species, (P. 

 crassa, p. 132, pi. viii, fis. 26, 27) which is apparently generically distinct from 

 any of our forms, and might be considered the type of his restricted genus. 



Molander (op. cit. 1915) judiciously adopted Gersemia (it being prior to 

 Vceringia Dan.) for the group typified by G. fruticosa, but he still retained 

 Eunephthya to include the glomerata group (Drifa), together with the florida- 

 group, named Duva by Danielssen. I believe that these two groups should be 

 separated as genera, but Eunephthya should not be used for either of them.

 Plate V; Figs. 1, la. Type. 



This was briefly described by me in 1865, in Proc. Essex. Inst., Salem, Mass., 

 Vol. IV, p. 151, and more fully, with some figures, in the same volume (p. 192, 

 figs. 8-8b); and later, in 1869, the characteristic spicules were described with 

 their measurements. The larger original specimens seem to have been destroyed 

 in the great Chicago fire. 3 



However I still have microscopical preparations from the type-specimen, 

 including the spicules now figured. I also have in my collection, a small co- 

 type, in good preservation. This, so far as I know, is the only one remaining. 

 This specimen is 25 mm. high and 10 mm. broad. The naked stalk occupies 

 about half the height. The whole forms a thyrsoid or club-shaped polypidom. 

 The polypiferous part is thyrsiform, with about a dozen crowded, short, clavate 

 larger branches, entirely covered by the polyps, which are closely crowded, 

 thirty to forty standing on each branch; below these there are several small 

 or incipient branches with three to ten polyps, and some polyps stand singly 

 or in pairs on the upper part of the stem, and, also, sometimes on the branches. 



'It does not agree with typical Capnella Gray (Ann. & Mag. Nat. Hist. Vol. Ill, p. 129, 1869), type 

 Ammothea imbricata Edw. Gray says the outer surface is studded with small flat, smooth, irregular- 

 shaped spicules and that the cells are "campanulate slightly eight-lobed" also that the polyps are retrac- 

 tile, all of which are very different in Eunephthya (typical).

3 Most of the collections of the North Pacific Exploring Expedition of which I wrote had beenTeturned 

 to Dr. Wm. Stimpson, naturalist of the Expedition, and then Director of the Chicago Museum, before 

 that Museum was burned with all its valuable collections. A few duplicates were previously deposited 

 in the Museum of Comparative Zoology, where they are still preserved. Among them are co-types of 

 the large Spongodes gigantea and S. capitata, and a few other Alcyonaria, but not E. thyrsoidea.
