Diastylid^e. - 
i)r. F. Muller (Arch. Naturgesch. xxxi. p. 311) reviews the 
literature of this family of Crustacea, which he considers to he 
necessary, as various opinions appear to exist among carcinologists 
as to the true position of the animals. The author’s criticisms 
are mostly directed against the observations of Prof. Van Bene- 
den, who he thinks has not shown his usual ability and accu- 
racy in his memoir on this group in his ^ Recherches sur la Faune 
Littbrale de Belgique.’ The author defends the observations of 
Kroyer and Goodsir, and thinks that their researches deserve a 
larger amount of credence than appears to have been given them 
by carcinologists. 
Hr. G. O. SARshas published (Vid.-Selsk. Forhand.for 1864) 
a monograph on the Norwegian species of the aberrant Crustacea 
Cumacea, with full deseriptions. These consist of twenty-five 
species, belonging to nine genera. He divides the genus 
Diastylis into two divisions : — 
a. Ocidus distinctus : — Diastylis rathkii (Kroyer), Sars, /. c. p. 36, taken at 
the Lofoten Islands ; D. lucifera (Kroyer), Sars, 1. c. p. 36, Gulf of Christiania ; 
D. hispinosa (Stimpson), Sars, 1. c. p. 39, Gulf of Christiania and the western 
shores of Norway (this species the author states to be synonymous with D, 
echinatm, Sp. B.) ; D, iumidee (Lilljeborg), Sars, 1. c. p. 43, Gulf of Chris- 
tiania. 
b. Oculm mdlm : — D, ampullacea (Lilljeborg), Sars, I, c. p. 60, from
