by him. So this Palmijuncus anguinus appertains to Eucirripathes spiralis (Blainv.) v. P., with 
which Pallas has very rightly combined it. Both the other species, also figured by Rumphius, are 
ignored by Brook, although especially these ones are very like Eucirr. anguina in the typical, 
sinuous axis. Especially for Palmijuncus striatus there can be no doubt about this likeness; 
however foi Palm, vulgaris there is room for doubt since Rumphius’ description is somewhat 
vague, and only the basal part of the colony is figured by him. This basal part is very like 
the colonies of Eucirr. anguina but the toppart, according to Rumphius’ description is: “een 
dunne draad met veel bochten en cirkels”. This is entirely in disaccord with the top of Eucirr. 
anguina Dana and for this reason (i. a.!) I prefer to identify Palmijuncus vulgaris with Eucirri¬ 
pathes Rumphii v. Pesch rather than with Eucirripathes anguina (Dana). 
The top of Dana’s specimen of Eucirr. anguina (Dana), is, according to Dana’s figure of 
the colony, not of the typical shape of the Siboga-specimens and tapers swiftly but gradually. — 
The specimen, figured by Gray in Proc. Zook Soc. 1856—57 are remarkably like the Siboga- 
specimens. The figured colony is entirely like the irregularly sinuous colonies of Eucirr. anguina 
(Dana), while the dried “bark” figured by Gray is in every respect similar to the dried parts of 
the Siboga-specimens. Without any doubt Gray’s species is to be identified with Eucirr. anguina 
(Dana). Cirr. gar diner i Forster-Cooper is united with this species on grounds which are fully 
given in the critical review of formerly described species.

This complete colony is 5.5 cm. high, with a length of 9 cm. measured along the axis. 
I he first half is irregularly curved; the upper half is a coil of a sinistrorsal spiral. The basal 
diameter of the axis of 360 p increases to 405 p at a height of 3 cm.; afterwards the diameter 
remains subequal, to diminish, scarcely at a distance of 1 cm. from the top, swiftly to the 
slightly damaged blunt apex (diameter 225 p). The basal plate is darkbrown with a lightbrown 
border and an irregularly oval outline; the axial canal is at the top only 13 p on diameter. 
The base of the colony is almost entirely smooth; on a little higher level the spines 
are well developed; their distribution is irregular here. They are conical, with a smooth surface, 
and 75 p long. This length increases gradually, while a different length of the spines on opposite 
sides of the axis puts in appearance and the distribution becomes more regular. The longer 
spines (135 p) are blunt conical, the smaller ones (80 p) are acute conical (fig. 206). The top 
of the spine is often slightly granulated. The mutual distance is from 420 to 490 p, so that 
the quincunx, which sometimes may be observed, is ever and again shifted. There are 5 
longitudinal rows, but usually this regularity is rather small, also in the higher parts of the
