Having recently shown (1) that in some of the Eryonidea the 
sperm is carried by the females in large external masses of sper- 
matophore nature and not in preformed receptacles as thought to 
be the case in some Erytridea as interpreted by GEOFFREY SMITH, 
it was of interest to find that in two of the members of the 
neighboring group, Scyllaridea, there are likewise spermatophore 
masses of the same general nature. Examination of these forms at 
Montego Bay, Jamaica B. W. I, showed the presence of large sper- 
matophore masses and the absence of any sperm receptacle. 
Female specimens of the large spiny lobster, Panulirus argos 
LATREILLE, were found with very conspicuous spermatophore masses 
on the under side of the thorax between the fifth and fourth legs 
in the position indicated by the dark area in Fig. 1. On a female 
40 em long and with antennae 48 cm long the sperm-carrying masses 
were 44 mm wide, 45 mm long and 5 mm thick. This material looks 
like dark, grey-black rubber smeared thickly across from the bases 
‘of the legs on the right to those on the left, posterior to the third 
pair. It is smooth and firm on the surface, except where it may
