Verrill thus mentions both the two tvpes of sclerites from the zooid boily. He states, however, that the scaledike type is the most common whereas the opposite proved to be the case in the "Ingolf" col- lection ; but this is a point to which no imjiortance may be attached as Deichmanx in 1936 (p. 234) not at all mentions this scaledike ty])e from the zooids though she re-examined Verriij/s specimen. In the specimens taken by the ""Ingolf" the scale-like scleriti's also occurred in a verv var\ing nundier. The measures, which Verrill states for the sclerites, agree also well with those of the "Ingolf" collection. It is true that the greatest length, which he mentions for the scale-like ty])e from thi' zooid body, is only ; on ])1. 2 fig. 4 6, c a scierite is, liowex'er, figured which after the magnification scale may have been mm in length. When Verrill (p. 22) states "'The tentacles are not entirely retractile" this may allude to the fact that tlieii- hiwer liaKes are coalesced. Dkii' (p. 234) states that the zooids are "with lew s]iicules", an information which does not. agree with the condi tions in the "Ingolf" specimens, and, also seems to be iii contrast with Verrill's figure pi. 2 fig. 4 n. The specimen, upon which Verrill's deseriptioii was nianilx based, lacks the base, but Verrill (I8,s;J ]). 22) describe
