twenty-four, viz., forty-two, It should, however, be noticed that my 
article gives, at different points, full titles of twenty-five works deal- 
ing directly and of seven others dealing less directly with Sponges, 
and records matter relating to Sponges of “/irty-one others, with- 
out giving their titles. Thus the total of works recorded is sixty- 
three, and not eighteen, as might, perhaps, be inferred from the 
wording of the review. 
“T am therefore unable to see (with one small exception) any 
validity whatever in the grounds given for the statement that, as. 
regards the literature of Sponges, the student would find the 
English Record imperfect.”—&. C. Rye, editor Zoöl. Record, 7 
le Row, London, 14 April, 1883. 
[We gladly make room for the foregoing reply to our notice in 
the April number of this journal. The notice of the English 
Zoological Record was prepared in a kindly, appreciative spirit, 
least of all was it the reviewer’s design to make a “ disadvan- 
ficing spirit is sufficiently evident. We should say frankly that 
we did not read with care the body of either reports, but com- 
pared the lists of works printed at the beginning of each chapter. 
By overlooking, as in the case of the sponges, mention of those 
Papers not enumerated in the English Record under.“ Chief 
Works,” we gave, as Mr. Ridley shows, an erroneous impression 
as to the completeness of the record, which we sincerely regret. 
At the same time, it seems to us other persons might fall into the 
Same error, and suppose that no author was mentioned whose 
writings were not catalogued at the beginning of the several 
chapters or sections. If the names only, of authors of minor 
Papers and notes could be added at the end of “ Chief Works,” 
etc, it would take but a few lines and be a great convenience. 
Apparently the German recorders have catalogued the author’s 
writings, both “chief” and minor articles and notes, referring by 
number to the catalogue number, and thus secured a greater ap- 
mar of accuracy.—A. S. Packard, . Fr., for Editors NATUR-
