and is separated from its partner by the genital process (sensu stricto), homo¬ 
logous with that of the female. Both Kane (1892), and Wilson (1915, Plate 
XXIX, fig. 22), in which I believe he follows Dana, call these genital plates 
spermatophores. I do not see how they can possibly be such. They do not 
appear to me to be solid bodies, nor to contain any contents, but merely 
spoon-shaped expansions with their concavities facing inwards, towards one 
another, and, as such, capable of grasping the spermatophores when partially 
extruded and ready for insertion in the female. Moreover as my females 
bear egg-strings I presume the eggs are fertilized, which predicates that the 
spermatophores have already been deposited (Fig. 9).

The genital process (Fig. 10) bears anteriorly a small rounded projection 
having a pair of small spines before and a pair behind it, and, posteriorly 
between the genital plates, two small apertures, one in front of the other, 
whose significance I have not at present determined. 
The Nervous System (Fig. 11) consists of a supra-oesophageal ganglion 
and an infra-oesophageal ganglion connected with one another by paired 
oesophageal commissures which run round either side of the oesophagus. 
The supra-oesophageal ganglion , dorsal to the oesophagus, is very noticeable 
in a preserved specimen not specially stained or treated, situated close behind 
the eye, which is half the size of the ganglion. The latter is pigmented with a
