Both the species named have been admirably studied by 
WirEN 1892, and I therefore find no reason to subject the pre- 
sent specimens to a renewed investigation’). 
Simrothiella Piussry 1898. 
_ Solenopus Koren & DanIersseN 1877 (not SCHONHERR 1826), partim. 
Simrothiella was constituted by PiLssry in 1898 as a subgenus 
of Proneomenia to comprise two types of Solenopus which had 
been established by Koren & Danietssen in 1877 under this name, 
which, according to the rule of priority, must be dismissed as 
pre-occupied. The two types in question were subsequently 
examined by Hansen (1888), who found that they agreed with 
the Neomenia in having gills but were distinguished from this in 
possessing a radula. After examination I have come to the con- 
clusion that one of the types has been erroneously described by 
Hansen and that it really belongs to the genus Dorymenia ; in the 
other, however, S. margaritaceus, true gills and a powerful radula 
are present (figs. 1, 2, 16). This form, the characters of which 
distinguish it from all the known genera of Solenogastres, must 
be established as the type of a distinct genus to which Prssry’s 
appellation suitably may be applied. 
As a result of my examination, the genus Simrothiella may 
be diagnosed as follows:

N. carinata.
