on J). 299 et seqq. The outcome is that the name Scala (Humph.) 

 Auct. is used in place of Scalaria. 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 ScHtelluiicke Addisoniida', CoccHluikht;, 

 families the elucidation of which is almost wholly due to Dr. Dall. 

 On p. 851, Turbo pnlchellus 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. palla recognized as a distinct 

 varietv by many European authors. The name brevis has also been 

 twice used in Pliasianella, both later than the date of Adam's 

 species. The anatomical description of Pleurotomaria, and the 

 parts relating to the Docoglossa and Chitons are especially interest- 

 ins: 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 comliination with his specific names 

 throuo-hout this work. The numerous plates are finely executed 

 photo-lithographic reproductions of drawings by Dr. J. C. McCon-

Contributions to Science, by C. J. Maynai'd. 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, fiisca and nitela Maynard are certainly 

 one species ; S. einerea, pallida and negleda Maynard = S. glans 

 Kiister ; S. picta INIayn. = marmorata Pfr. ; S. ianthina Mayn. = 

 alvearia var. rubicunda Mke. ; etc., etc. The author should consult 

 the works of Leidy or Binney before jniblishing 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. incana in Terr. Moll, i I). We trust that before a second fiis- 

 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 Pfeifier and other German and French authors 

 on this genus, and indicate the differential characters of his 

 .species.
