Gonosome. — Gonophores borne on long, unbranched peduncles, at- 

 tached to the hydranth just distal to the proximal tentacles, each 

 gonophore with a short pedicel ; apparently these gonophores develop 

 irregularly, as small and large ones are mixed without any evidence 

 of their appearing in any regular order. 



Type.—V.^.'^M. No. 43452. The vial is labeled "U. S. F. C. Str. 

 Albatross, Panama, Mar. 12, 1891," but there is no station listed on that 

 day. The last haul on March 11 was made in latitude 7°33' N., 

 longitude 78°34'20'' W., in 85 fathoms. 



Remarks. — The adventitious shoots in these hydroids are so unusual 

 that it might seem advisable to place the species in a new genus, but, 

 although each of the three specimens available for examination had 

 these shoots, it is just possible that they may have developed under 

 unusual conditions, and as all the other features are definitely like 

 Corymorpha, it seems better at the present time to place it in this 

 genus. 



Family TUBULARIDAE 

 Genus LAMPRA Bonnevie 



LAMPRA UVULARIS, new species 

 Plate 14, Figure 4 



Trophosome. — ^Zooid 22 mm., of which the hydrocaulus is 15 mm., 

 straight, without annulations; hydranths large, 7 mm. in diameter; 

 proximal tentacles 18-20, long and slender; distal tentacles 40-48, 

 shorter and stiffer in appearance, in four rather indistinctly different 

 whorls. 



Gonosome. — Gonophores growing in eight erect, closely arranged 

 clusters, looking like compact bunches of grapes or like the cluster 

 of flowers in the grape hyacinth; each gonophore is spherical, on a 

 short pedicel, and shows no sign of tentacular processes. 



:7'y^e._U.S.N.M. No. 43453. Taken by the United States Fisheries 

 steamer Albatross at station 4253, Thistle Ledge, Stephens Pass, 

 Alaska, 131 fathoms, July 14, 1903. 



Remarks. — This appears to be the first record of a species of this 

 genus from the northeastern Pacific. This is not the place to discuss 

 the systematic position of Lampra, but it may be stated that it cannot 

 be placed in the Tubularidae (as Bonnevie has placed it^) as this 

 family has been defined in all my previous papers.
