Irregularly ellipsoidal. Whitish, in the interior yellowish. 



Large amphioxes: 2.8 mm. by 50 /u. Small amphioxcs: in the choanosome 

 among the large ones; 300 by 9 pi. Orthoplagiotriaenes: rhabdome over 3 mm. 

 long, about 50 p. thick; clades either concave to the rhabdome throughout or 

 curved in the opposite direction distally, 300 /i long. Mesoprotriaenes : rhabd- 

 ome 3.7 mm. by 10 //; clades over 150 p. long. Anatriaenes: rhabdome 20 p 

 thick and about as long as the mesoprotriaene-rhabdome; clades strongly re- 

 curved, 80 p long. 



Large subcortical asters: rare; rays numerous, rather stout, rough, cj'lin- 

 droconical and blunt; total diameter 30 p. Small choanosomal asters: rays 

 pointed or blunt; total diameter 17 //. Small dermal sphaerasters: total cHame- 

 ter 12 /i. Sterrasters: 70 by 55 /i. Sterroids; with distant rays. 



Western Pacific. Ternate. 



Geodia amphistrongyla Lendenfeld. 

 Ante, p. 175. 



Irregular, flattened. In spirit: brown. 



Large amphistrongyles : 0.5-2.3 mm. by 18-32 p. Large styles: rare; 

 dimensions as in the amphistrongyles. Plagioclades: mostly triaene; rhabdome 

 1.8-2.2 mm. by 22-32 /i, sometimes much reduced in length, usually rounded at 

 the acladomal end; clades concave to the rhabdome, 155-190 p long; clade- 

 angles usually 103-120°. Mesoproclades: mostly triaene, occasionally mon- 

 aene; rhabdome 3-5 ju thick, clades 40-60 /i long; clade-angles 36-41°; epirhabd 

 16-23 p long. Anatriaenes: rhabdome 1.5-4 p thick; clades 26-50 p long; 

 clade-angles 25-41°. 



Oxyasters: from five to nine usually simple, rarely bifurcate, distally spined 

 rays, 0.8-2.1 p thick; total diameter 20-30 p. Oxysphaerasters : from fourteen 

 to eighteen conical, distally spined rays, 2-2.8 p thick ; centrum 6-7 p, whole aster 

 19-28 p, in diameter. Small strongylosphaerasters: from seven to twelve cylin- 

 drical or distally slightly thickened rays, 0.8-1.8 p thick; centmm spherical or 

 irregular, 2.2-4 p in diameter; total diameter 4.8-8 p; a few have more rays, 

 these perhaps foreign. Sterrasters: 100-110 by 87-94 by 72-78 p.
