" (1896) of a specimen from the Bay of Biscay as Calyp- 

 " terinus Allmani, Versluys (p. 93) remarks that the 

 ' ' specimen differs from the type of that species in having 

 "more scale-like coenenchym spicules, ' mehr schuppen- 

 " artigen Kinden-Scleriten.' 



" In this character, as well as in the character of 

 "having nine (or more) zooids in a whorl, the Caudan 

 " specimen seems to agree with the specimen from Ire- 

 " land and differs from the other species. 



" Our specimen clearly differs from the specimens re- 

 ' ' f erred by Studer (1901) to Stachyodes Josephinae 



(Lindstrom) and S. trilepis (Pourtales) from the Azores. 

 "As Versluys (1906) has shown, S. Josephinae belongs 

 " to the genus Calyptrophora, and the specimen described 

 " by Studer as S. trilepis is probably new. The latter 

 " differs from our specimens in the character of its rami- 

 " fication and in the small number (4) of zooids in a 

 " whorl. 



" The description of S. regularis (Duch. and Mich.) 

 " from Guadeloupe is so imperfect that it is, perhaps, 

 " uncertain whether our species agrees with it or not. 

 ' ' It certainly agrees with our specimen in having 

 " numerous (up to 10) zooids in a whorl, but appears to 

 " differ from them in the small size of the basal scales, 

 " and in being branched. 



"In conclusion, it may be said that it is clearly con- 

 ' ' venient to regard the Irish specimens as constituting a 

 "new species, that the specimen described by Koule 

 "' (1896), and obtained by the Caudan in 1,220 and 

 ' 1,400 metres in the Bay of Biscay, probably belongs to 

 " the same species, that the closest affinities of the species 

 " are with S. dichotoma (Versluys) and S. Studeri (Vers- 

 " luys) from the Pacific Ocean and East Indian Archi- 

 " pelago, that it differs from these last-named species in 

 ' ' in the large number of zooids in each whorl , and in the 

 "character of the coenenchym spicules. In recognition 

 ' ' of the great value of his contributions to our knowledge 

 ' ' of the Primnoidae , I propose to name the species 

 " Stachyodes Versluysi. 



" Note. I wish to refer to an additional character I 

 "have observed in this species. The aboral surface of 

 ' ' the tentacles is armed with a crowd of small spicules 

 " from the base to a short distance from the apex. These 

 " spicules vary considerably in size and shape. The 

 " longest are about 0'2 mm. in length, and the smallest 

 "minute stars. They appear to be usually very thin, 

 "the longest are spindle-shaped in outline, the smaller 

 ' ' ones diamond-shaped ; but they are all characterised by 

 " their very sharp tubercular processes. Many of them 

 "are disposed parallel to the long axis of the tentacle, 

 " but most of them are quite irregularly placed. There is
