SUMMARY OF CURRENT RESEARCHES RELATING TO 
front ; the crown has a simple wreath of cilia and two lateral ear-lobes, 
each with a finger-shaped palp with a hint of segmentation ; on the 
middle field of the crown are eight bluntly conical prominences with 
sensory hairs ; the foot is borne ventrally at the beginning of the 
posterior third of the body ; the eye is simple and occipital ; the mouth- 
parts have weak jaws, the hypodermis is vacuolar ; there is a Y-shaped 
thickened shield on the back. Of the third species, only the female is 
known. It has an almost cylindrical body, a distinctly defined head, a 
characteristic cap-like head-shield, a crown with five finger-like palps 
and two sensory tufts, and lateral antennae on the posterior third of the 
body. 
Adinetidae.* * * § — Mr. D. Bryce has some general notes on this group of 
Rotifers ; in moss-washings no species is of such general occurrence as 
Adineta vaga , on which his observations have been chiefly based. He 
describes A. clauda sp. n. from a single specimen obtained at Gareloch- 
head, N.B., where it lives in moss. By its sucker-like foot it is allied 
to Discopus, and perhaps it is the type of a new genus. 
Notes on Rotifers.} — Mr. G. Western finds that his Pleurotrocha 
grandis is synonymous with Diglena ferox. Philodina commensalis sp. n. 
was found on Asellus vulgaris from Putney, Wandsworth, and Epping 
Forest. Mr. Hood has sent the author examples of the male of 
Stephanoceros Eichhorni , ’which has never yet been recorded. Notholca 
Hoodi sp. n. was taken in sea water at Westport, Ireland ; Pattulus 
bicornis sp. n. was found at Roehampton, and is common in Scotland 
and Ireland ; Callidina sordida sp. n. is a large form, which was found 
in moss that came from Epping Forest. 
Phoronis from Port Jackson.} — Prof. W. A. Haswell reports that, 
in addition to the large Phoronis australis which he described eleven 
years ago, he has lately found a smaller species of the same rare genus, 
in which he can find hardly any point of importance to separate it from 
P. psammophila from Messina; the most important distinctions are the 
greater number of tentacles (about 100), and the absence of sand-grains 
from the tubes. 
Minute Anatomy of Rhodope Veranii.§— Dr. L. Bohmig treats in 
detail of the minute anatomy of this much discussed organism. In his 
opinion the facts of its development are opposed to its being one of the 
Mollusca, while those of its structure support the view. On the other 
hand, if we compare it with the Turbellaria we find it has a digestive 
apparatus which consists of three portions and opens by an anus which 
is placed on the right ; the central nervous system is broken up into a 
pair of cerebrovisceral ganglia, a pair of pedal and a pair of buccal 
ganglia ; three commissures surround the fore-gut. The excretory 
system is without the ciliated infundibula which are characteristic of 
the Piatyhelminthes, and, in position and structure, is much more like 
that of the Nudibranchiata ; the chief part of the genital organs is repre-
