14 CURRENT LITERATURE. 



JVeoja/tella dubia, Ckll., 1891. On this latter genus and species Mr. Hedley 

 makes some rather strong remarks. Personally we consider it doubtful, on the 

 grounds that a new genus and species described from a single alcoholic specimen 

 — and not in the best of condition either — unaccompanied by figures or anatomical 

 details, has no claim to acceptance, and should never have been described. 



A new colour variety of A. graffci is described, viz., v. now rosea. " Entire 

 animal coloured bright melon-pink. Summit of Mount Bellenden-Ker, N. Q. 

 (K. Broad bent) and Prosperine River, X. Q (C. \Y. de Bergh Birch.)" 



There are one or two errors which it will be well to point out. /. papillata is 

 wrongly placed as a var. of/, bitcutaculata, and J. verrucosa and marmorata are 

 both credited to Von Martens. I speak subject to correction, but think Simroth 

 was the first to describe these. — W. E. C.

A valuable contribution to our British shells. One or two criticisms may be 

 made however. Trochus magus v. conica, Mar., appears identical with v. producta, 

 Bucquoy, Dautzenberg, and Dollfus, which is described as narrow, spire very 

 elevated and umbilicus very small ; this species is of course not a true Trochus. 

 Rissoa pulcherrima \. pcllucida. Mar. ; there is a v. con color, B.Ik and I)., described as 

 yellowish white without markings, these two can hardly both stand. On R. cingillus 

 v. grapkicus, it may be remarked that while the yellowish form is found at Wey- 

 mouth, the white is abundant at Portland. Puliina philippii V. tuiuidosa, Mar.; 

 the author states that "This variety I had originally named in MS. until after the 

 publication of the "Challenger" Report, when I recognised the E. latipes of 

 Watson, described and figured therein as the same thing." Surely Mr. Marshall 

 cannot intend to refer E. latipes of Watson to his MS. name of v. tiiniidosa. 

 Cerithuopsh tubercularis v. acicula, Brusina ; according to Bucquoy, Dollfus, and 

 Dautzenberg this is v. subulata, Wood. Niassa reticulata v. minor, Mar.; there is 

 a v. curia, 1!. I). & 1 >. , squat only measuring 14 millim. Cypraa europceav. minor, 

 Mar.; there is already a v. minor, Monterosato. A protest must be entered 

 against these vars. minor, major, &c. ; unless they differ by some other 

 characteristic than size alone, they can surely be of no service, and we shall require 

 a name for every specimen which differs in size from the type. — E. R. S.

 Aug. -Oct., pp. 1S5-248, pis. 10-12. 

 These parts deal with Ortalicus, Otostomus, and part of Bulimttlus. The 

 spelling is changed from Orlhalicus on the ground that the derivation should be 

 from oprdXixos — a young fowl ; such an alteration as this, however, is dangerous, 

 as there is another possible derivation which would give Orthalicus, and since 

 it is now impossible to be certain which derivation was originally meant 

 it is better to keep to the original spelling. The following are new : — Ortalicus 

 maclnric, Otostomus trimarianus, O. bngabensis, 0. chanipioni, 0. moritinctus, 

 fiuliinulus durangoanus. The substitution of comparative tables in place of 

 a description of each species is a new and convenient feature. They are not, how- 

 ever, arranged as conveniently as they might be, that of Bulimulus for example is 

 placed in the middle of the letter-press relating to B. schiedianus, so that on 

 p. 239 we have only part of the references, on p. 240-1 the table of the genus, and 

 on p. 242 the remainder of the references. — E. R. S.
