Of the more characteristic forms of the genus Anthrapalcemon, as 

 defined by J. W. Salter, met with in Illinois, U.S.A., in Nova Scotia, 

 at Airdrie (Lanarkshire), Ipstone (North Staffordshire), Shropshire, 

 and Lancashire, it may he stated that the carapace is nearly 

 quadrangular, the frontal border being nearly straight, and only 

 a fifth less broad than the widest part of the carapace at its 

 centre ; the abdominal segments are short, hardly longer than the 

 cephalothorax, which is nearly as wide as the carapace itself. The 

 median ridge is well marked, also the cervical furrow ; the front angle 

 of the carapace has a sharp spine, and the rostrum is strongly produced

Schizopoda, some of which at least had been believed to belong to the Decapoda. 

 Dr. Caiman also expressed a doubt as to the determination of some of the species 

 referred to Crangopsis and to the Euphausidse ; but space does not permit us to 

 deal with these divisions satisfactorily here.

3 Anthrapalcemon Grossarti, Salter, was published in 1861 (see Q.J.G.S., 

 vol. xvii, p. 528, with woodcut), Palceocarabus Russellianus, Salter, in 1863 

 (Q.J.G.S., vol. xix, p. 520, figs. 1 and 2). I pointed out in 1866 (Trans. Glasgow 

 Geol. Soc, vol. ii, p. 246) that A. Grossarti and P. Russellianus were identical 

 species, and as the former had two years priority over the latter, the name 

 P. Russellianus must disappear and become a synonym of A. Grossarti, Salter; 

 see also Brit. Mus. Cat. of Brit. Foss. Crustacea, 1877, p. 8.
