Siboga-specimen from station 305 ; the other data, not always implicitly given by Thomson & 
and Simpson, are in accordance with the rest of the tabel. The authors record a likeness between 
their species and SticJi. lutkeni Br., which is joined by me with Eucirripathes spiralis. 
Stichopathes regular is F. C is in its characters, given in the tabel, well in accordance 
with the other specimens; the stem is regularly coiled, and, although Forster Cooper does not 
give a diameter of the coils, I deduce from his figure of part of the stem that the diameter 
of the coils is ± 1.25 cm. 
The diagnosis should be emendated as follows: 
Colony : entirely or for the greater part wound in a sinistrorsal spiral: 
coils-dia meter a few cm. (2 — 3); usually gradually tapering; un branched; 
base may be straight or sinuous; apex rapidly tapering. 
Spines : blunt cylindrical or conical, with rough knobby top; at right 
angles with the axis, or slightly distally inclined (especially the shorter 
spines and the more slender long ones); unequal length on opposite sides 
of the axis (o— 530 u . ; average: 300 g and 100 3); mutual distance ±500 p.; 
6(—9) longitudinal rows. 
P olyps : arranged in 1 to several rows; interpolypar distance 1 — 2 mm.; 
mouth rounded or irregularly folded. 
var. aphanipathoides v. P. 
Polyps: small, with knobshaped tentacles; oral cone not striped; length 
of tentacles 0.5 mm.; perforated by the spines. 
var. intermedia v. P. 
Polyps: on one and the same colony either like var. aphanipathoides , or 
like var. striata , but without stripes on the oral cone; length of tentacles 1 mm. 
var. striata v. P. 
Polyps: large oral cone with ten dark stripes; leadblue except the 
tops of the tentacles and the rest of the oral cone; length of tentacles 
0.5—1 mm.; polyps are not perforated by the spines. 
var. oligosticha var. n. 
Polyps: unknown; Spines: in 3—4 longitudinal rows. 
Pormer habitat: Pallas Indie; Ellis Moluccas; Brunnichen Norway (?); Baker 
Mediterranean (r); Ondaatje Ceylon; Murray Kurrachee; Stokes E. India; Rumphius Ambon; 
Schultze N. E. of Boavista, Cape Verde; I homson & Simpson Ceylon; Brook (Lutken)
