XVIII. PROTOZOA. 
The large number of papers marked with an * is unsatisfactory but it 
is difficult to see how this can be avoided. Almost all these belong to the 
section of the subject under discussion. 
The very rapid progress of our knowledge of the Sporozoa in the last 
few years makes a general treatise on the subject desirable. 
Laveran’s paper on the classification of the Hcemacytozoci should be 
helpful to students of this group. The numerous contributions by this 
author and Mesnil and by Leger have added much to the Literature of 
this section. 
Among other publications of the year the first place must be given to two 
general treatises on the Protozoa. The excellent volume by Lang (127) needs 
no commendation here. The other work, Calkins (26), calls for one or two 
remarks. It should help very greatly in interesting workers in the group. 
For a long time some treatise such as this has been badly needed and 
if the Author succeeds in inducing many amateur microscopists to take a 
more scientific interest in their hobby he will have done a good work by 
his book. This remark must not be interpreted as suggesting that the 
book is entirely popular, but only as indicating one direction in which it 
will be useful. The book is up to date and well written and illusti’ated. 
But the strongest possible condemnation must be passed on one point; 
two illustrations in the book (p. 41, fig. 13 b, & p. 251, fig. 134 d), bear the 
inscription “n. sp.” Footnotes to figures in a treatise are not the proper 
places for the publication of new species unless indeed the author desires 
them to escape the notice of the Zoological world. A useful review of the 
work (to which the Recorder is indebted for bringing this point to his 
notice) by Prof. Minchin will be found in Nature lxv, p. 433. 
Apart from the Sporozoa the progress made in the Protozoa is about 
the same as in previous years. As usual the Systematic Index of 
Foraminifera is larger than that to all the other groups combined. For 
the first time for many years an entry appears under the Proteomyxa. 
Sand has completed his Monograph on the Tentacidifera which has 
been appearing for some years in the Ann. Soc. Beige Micr. The whole 
work has now been issued separately and will be of help to those interested 
in this subdivision. 
In conclusion it may be noted that the feature of this Record is 
undoubtedly the preponderance of Biological over purely Systematic 
papers. More Systematic and Faunistic papers on Protozoa are indeed 
needed, but for the present interest seems to be concentrated on those 
branches of the subject dealing with relations the exact comprehension of 
which is of the utmost importance to Mankind.
