A8 THE NAUTILUS. 
on p. 299 et seqq. The outcome is that the name Scala (Humph.) 
Auct. is used in place of Sealaria. Any naturalist who has 
puzzled over similar cases will appreciate the labor spent by Dr. 
Dall on these three pages of solid synonymy, and be glad to accept 
without question his result. The rhipidoglossate series is commenced 
with the limpet-like families Scutellinide Addisoniide, Cocculinide, 
families the elucidation of which is almost wholly due to Dr. Dall. 
On p. 351, Turbo pulchellus C.B. Ad. is said to be synonymous with 
the later name Phasianella brevis Ad. If this be a distinct species, 
it cannot, nevertheless, be called P. pulchellus, for that name is pre- 
occupied by Risso for a form of Phas. pulla recognized as a distinet 
variety by many European authors. The name brevis has also been 
twice used in Phasianella, both later than the date of Adam’s 
species. The anatomical description of Plewrotomaria, and the 
parts relating to the Docoglossa and Chitons are especially interest- 
ing for the amount of wholly new information contained. We fail 
to see why Dr. Dall uses names admitted to be merely sectional or 
subgeneric in a generic sense in combination with his specific names 
throughout this work. The numerous plates are finely executed 
photo-lithographic reproductions of drawings by Dr. J. C. McCon- 
nell. 
ContrRIBuTIONS TO ScreNCcE, by C. J. Maynard. Monograph of 
the genus Strophia. This monograph seems to have been written 
without consulting the previous (somewhat extensive!) literature of 
the group. The author takes views of species rather narrower than 
we remember seeing this side of the Atlantic. In the dozen species 
described in this first fascicle perhaps not more than two or three, 
if that many, are really entitled to specific rank as species of this 
genus were understood by Pfeiffer. A casual inspection will con- 
vince any conchologist acquainted with Strophia that S. pannosa, 
levigata, festiva, intermedia, fusca and nitela Maynard are certainly 
one species ; S. cinerea, pallida and neglecta Maynard = S. glans 
Kiister ; S. picta Mayn. = marmorata Pfr.; S. ianthina Mayn. = 
alvearia var. rubicunda Mke.; ete., ete. The author should consult 
the works of Leidy or Binney before publishing such figures of 
anatomy as those on plate ii of this work, or such explanations; fig. 
10, for instance, is simply extraordinary (compare Leidy’s figures 
of S.ineana in Terr. Moll.i!). We trust that before a second fas- 
cicle of this “ Monograph” appears, Mr. Maynard will consult 
either a collection in which a majority of the species are represented, 
or the works of Pfeiffer and other German and French authors 
on this genus, and indicate the differential characters of his 
species.
