C. affinis, E. Hesse, 1878, Asierope oblonga, G. 0. Sars, 1887 and Cijlindroleheris oblonga, 

 G. W. MUller, 1894. Ill liis work of 1894, p. 219 this author does not include in his list of 

 synonyms of Cylindroleheris oblonga E. Hesse's two species mentioned above and the synonyms 

 Cypridina Mariae, W. Baird, 1850 c, a.nd Cylindroleber is Mariae, G.S. Brady, 1868 b, are denoted 

 with a query as being doubtful. 



G. S. Brady and A. M. Normax discuss in their work of 1 896, p. 630 a species Asterope Mariae. 

 With it they synonymize all the above-mentioned species included by G. \V. MCLLER, 1912 with 

 the exception of E. Hesse's two Copechaete species; all the synonymizations are denoted as certain. 

 — Other authors as well who deal with these forms, J. A. Cushman, 1906, C'H. Jlday, 1907 

 and R. W. Sharpe, 1909 make the same synonymization as G. S. Brady and A. M. NORMAN. 



I''ig. ('A. — Asieriipe Grimaldi var. vicina ii. sp. et var.. 5. — 1. Left valve seen from inside; 186 X. 2. Distal part 

 of tlie seventh limb: tlie cleaning l)ristles are broken; 656 X. 



In order to decide the relation of A. Grimaldi and the variety described above to the 

 above-mentioned forms and the nuitual relations between the latter I shall try to give here a very 

 much concentrated account and discussion of the descriptions and figures of the latter that are 

 found in the literature. 



The original description of W. Baird's Cypridina Mariae is found in this author's work 

 of 1850 c, p. 257. This description is very short and incomplete and only deals with the appearance 

 and length of the shell: ,, Carapace valves elongate oval, of exactly the same size at each extre- 

 mity; extremities rounded. Dorsal and ventral margins nearly plane or very slightly arched". 

 The shell is about 1,5 mm. long. It was foimd at the Isle of Skye, Scotland. Three figures 

 accompany this description, the shell as seen from the side, from above and from in front. The 

 description and figures only show that this author had a mature female or a larva of a species 

 probably belonging to the Grimaldi group of the genus Asterope.
