subspecies with the other type of dactylus must 
bear a new name. For this subspecies the name 
metaneomeris is not available, as it was at- 
tached by Coutiere to the type for S. strepto- 
dactylus and is a synonym. Therefore we here 
give to the subspecies described and named by 
Coutiere as S. metaneomeris streptodactylus 
( 192 1 : 4l4 ) the new name of S. streptodactylus 
hadrungus (from the Greek hadros, thick). 
The difference between the two subspecies 
lies in the proportions of the ungui of the 
dactylus of the walking legs. In S. s. strepto- 
dactylus the ventral hook is 2. 5-3. 6 times as 
long as thick at its base, its base is twice that 
of the dorsal, and its length is 1.5 that of the 
dorsal; in S. s. hadrungus the latter proportions 
are 2.0 and 3-6. (The proportions of the ven- 
tral hook alone were not reported, but, accord- 
ing to Coutiere’s 1921 figures, it should be 
about 2.5 times as long as thick.) In spite of 
this slight and subtle difference, and in spite 
of the variation in proportions usually found 
in this family and genus, none of the specimens 
in our collection was intermediate between two 
subspecies. In these specimens the range of 
proportions on the diagnostic characteristics 
are as follows (15 specimens from 4 localities 
were measured; the average measurements are 
given in parentheses ) : ventral hook, length- 
breadth, 1.7— 3-0, (2.2); length ventral hook- 
length dorsal hook, 1.0- 1.2, (1.1); thickness 
ventral hook — thickness dorsal hook, 1. 7-2.0, 
(2.0). Therefore all of our specimens are S. 
s. streptodactylus . 
Since the paper dealing with the additional 
reports on the Hawaiian alpheids appeared we 
have discovered S. s. streptodactylus in Hawaii. 
Here the species is abundant on the spongocoel 
of a large sponge, Zygomycale parishei ( Bower- 
bank) (de Laubenfels, 1950: 25). Previous re- 
ports on the species do not note any association 
with sponges, and if the non-Hawaiian speci- 
mens in the collection were associated with a 
sponge, the sponge was not a distinct massive 
sponge but was one found in the branches of 
dead coral heads.
