Fig. 1. Anthomastus fisheri n. sp. Spicules: a, of anthocodial wall; b, of tentacles; c, of pharynx; d, of canal walls 
of stem interior; e, rods of stalk wall; /, stellate bodies from outer surface of stalk and capitulum. Scale applies to 
all figures. 
which have the median waist elongated, to- 
gether with rods and spiny-headed clubs 
(Kg. 1 . In the tentacles there are flattened 
rods which often have a club-like expansion 
at one end (Fig. 1 b), and in the gullet there 
are smaller, flattened spiny rods, often with 
one or both ends expanded (Fig. 1 c). 
The color of the colony in alcohol is 
"ferruginous” (Ridgway); the spicules are 
practically colorless by transmitted light, but 
appear pale amber in color by reflected light.

REMARKS: Anthomastus steenstrupi Wright 
and Studer, with which Nutting erroneously 
identified one of these Hawaiian specimens, 
differs from A. fisheri n. sp. in spiculation and 
in form of the colony. The new species has 
more slender, needle-like spicules and more 
compact, stellate sclerites, and its capitulum 
is spheroidal, whereas that of A. steenstrupi is 
"very slightly convex” (Wright and Studer) 
on the upper surface. Anthomastus fisheri re- 
sembles A. granulosus Kukenthal (1910: 14, 
pi. 1, fig. 3), but that species differs in its 
granular spheres and double spheres, and in
