Spines . laige, blunt, conical, granulated surface with small protube¬ 
rances on the apex; according to fig. ± 7 irregular longitudinal rows, and 
according to description:^ regular spirals. — Very smallspinesdistributed 
irregularly between the larger ones. 
Polyps: white. Digitiform tentacles. On one side of the axis. 
11. Stichopathes longispina F. Cooper. 
The description is not very detailed, so that only a rather vag'ue diagnosis can be given, 
and no identification can be tried. 
Colony, straight, whiplike, tapering; basal diameter 1 mm. with a length 
of 92 cm. 
Spines, longest ones: 400 500 p., shortest ones: 140—170 p,; smooth (?), 
aiianged in 7 longitudinal rows; long spines nearly at right angles with 
the axis, short spines distally inclined. Acute. M utual distance 550 p. 
Polyps: flat with long digitiform tentacles; crowded; diameter 0.75 mm. 
12. Stichopathes alcocki F. Cooper. This species is nearly related to Eucirripathes 
spiralis ; cf. my fig. 216 with Cooper’s enlarged spine in his fig. 3 (20). — However the very 
vide axial canal, so that the corallum-wall is reduced to a thin shell, is never present in 
Eucirr. spir. — Also the small spines between the larger ones are not found in the latter 
species. — In other points Cooper’s species is so very like Eucirr. spir. that perhaps Stich. 
alcocki ought to be regarded as a variety of the Eucirripathes in question. — For the present 
we will keep this Stichopathes intact with the following diagnosis : 
Colony: a close spiral: the central canal of the axis is so very large, 
as to reduce the wall of the corallum to a thin shell. 
Spines: 10 longitudinal rows; short (200 p„), sharp and hooked upwards, or 
longer (300 p.) and bluntly conical, at right angles with the axis; both roughe¬ 
ned. Secondary spines: sharp, triangular, irregularly scattered. 
Polyps: largest ones 1 mm. in diameter; very flat; tentacles long, digiti¬ 
form; prominent oral cone. 
13. Stichopathes seychellensis F. Cooper. Diagnosis: 
Colony: straight; tapering gradually; basal diameter 1 mm. with a colony- 
length of 45 cm. 
Spines: 5 longitudinal rows: leng'th 200 p. and 100 p. on opposite sides of 
the axis; at right angles with the axis, or distally inclined; concave sides; tri¬ 
angular; smooth (?). 
Polyps: round, prominent; circular mouth on a domeshaped oral cone; ten¬ 
tacles conical; sagittal tentacles inserted at a lower level; length of tentacles 
1 mm. (?); interpolypar distance 1.3 mm. (?).
