-\s neither desiTiptions nor tigures have been given nnthine can he said witli ccitainly 

 about the relation of the I'ollowing forms to the forms treated above: (Jylindroleberis Mariae,

 1902 b, pp. 497, 509, 511, 517; Marine Biological Association, 1904; C. H. OsTRNFELD, 1906, 

 p. 96; C. H. OSTE.NFELD and < '. \V!:8ENBERG-LUM>, 19(»9, ]). 112; A. M. NOHMAN and (i. S. 

 Brady, 1909, p. 359. Asterope oblonga, K Graeffe, 1900, j). :U. Cijlimlroleheris oblonga, d W. 

 MCLLER, 1908. p. 94: 0. de BIjE.N, 1916, p. 365. 



In order still fiu-ther to illustrate the uncertainty that exists with regard to the synonym- 

 ization of forms belonging to this group the following facts may be added. I applied to Professor 

 G. S. BradY' for specimens of A. Mariae so as to carry out a verificatory investigation. A tube 

 containing a number of imlividuals, defined by Professor BHAi)\ as A. Mariae, was kindly 

 sent to me by this investigator. As will be seen in the remark imder A. aberrata, p. 508 of this 

 treatise, all the specimens except one turned out to belong to the latter species, which is of course 

 a form that is fairly well differentiated from species of the Grimaldi group with regard to the 

 type of shell, etc. The specimen that did not belong to A. aberrata was a larva, a male in the 

 penultimate larval stage, which thus did not permit of certain identification of the species, but 

 I do not hesitate, however, to state that it is very probable that it belonged to A. norvegica. 



Since, as has been shown above, both Cypridina Mariae W. Baird and C. oblonga 

 E. Grube are too incompletely described to allow of qmte certain identification of these species, 

 it seems undoubtedly best, at least for the present, to reject these two names of species 

 in order to avoid further confusion. Only if it should turn out that fully identifiable type- 

 specimens are still in existence or if only a single form of this type were to be found at the 

 type localities, the Isle of Sk}-e in the case of C. Mariae and Cherso Island in the Adriatic Sea 

 in that of C. oblonga, ought these names to be adopted once more.
