Psammoryctes, g. n., Vejdowsky (11), differs from the other Tubificidce 
(Tub if ex and Limnodrilus) through the possession of 4 types of bristles —

several anatomical characters (no cutaneous vessels, segmental organs 
without ampullae, seminal duct opening in a seminal vesicle, and continued 
as coemental duct to the atrium of the penis ; spermatophores Opalina- 
like, with a hooked trunk, reminding of an Echinorrhynchus, &c.). Type, 
P. umbellifer, Kessl. 
Phreatothrix, g. n., id. (13). Agrees with Trichodrilm, Clap., 
through the position of the receptacula seminis behind the seminal 
ducts ; it differs through the presence of a single pair only of these 
receptacula, but of two pairs of seminal funnels, and two pair of testes 
(6fch to 15th segments) ; lateral contractile vascular loops terminating in 
two blind appendages ; bristles simple, delicate, in two double rows on 
each side of the body, as in Trichodrilus. T. pragensis, sp. n., id. (Tri-
