630 SUMMARY OF CURRENT RESEARCHES RELATING TO 
New Species of Pristina.* — Dr. A. Garbini describes Pristina affinis 
sp. n., nearly allied to Beddurd’s P. proboscidea. He found the Oligo- 
chtete in studying Utricularia neglecta which sometimes captures it. 
The proboscis (prostomium) is very long, almost cylindrical, and very 
delicate and mobile. 
Abyssal Sipunculids.f — M. Louis Roule makes a preliminary note 
on the Sipunculids collected by the ‘ Travailleur ’ and ‘ Talisman ’ from 
depths of 958 to 4255 m. in the Atlantic, off Spain, Morocco, and 
Senegal. Two genera were represented in the collection, — Phallosoma 
Levinsen, nearly related to Sipunculas , and Phascolosoma. In regard 
to the latter in particular, the author expresses his strong doubt as to 
the value of specific distinctions previously suggested. It appears to 
him to be a very plastic type with numerous local varieties connected 
by transition-forms. 
South African Gephyreans.J — Dr. C. Ph. Sluiter gives an account 
of the Gephyreans obtained by Prof. Weber in Africa; the collection 
contained six species only. The greater part of the paper is taken up 
by a description of a Malay form previously described by the author § as 
Sipunculus indicus Peters, but now formed into a new species as S. dis - 
crepans. The two species differ in several points, notably in the minute 
structure of the skin, which is described and figured in both. 
Rotatoria. 
Rotatoria of the Basin of the Lake of Geneva. || — Dr. E. F. Weber 
publishes the first part of what promises to be a very valuable contri- 
bution to the rotatorial fauna of Switzerland. This first part contains 
a descriptive list, with synonyms and bibliography, of 17 Rhizota and 
18 Bdelloida so far found by the author in this district, and every species 
is illustrated with excellent original and coloured drawings. One species, 
Callidina brycei , is described as new. 
New Rotifer, Monostyla appendiculata.^f — Mr. A. Skorikow of 
Charkow, figures in outline and describes as new this rotifer which he 
found in an inland salt-water lake in Russia. Unfortunately, this new 
species was already figured and described by Dr. E. von Daday in 1893, 
under the name Monostyla lamellata , from salt-water lakes in Hungary. 
Nematohelminthes. 
Introduction to Study of Nematode Parasites.**— Mr. N. A. Cobb 
has made a laudable attempt to popularise the study of nematode para- 
sites which he has already greatly advanced. After a description of 
methods of observation, he gives a general account of the structure and 
functions, most liberally illustrated. Eight new genera are proposed ;
