Description: — F c m ii 1 (>: — 



Shell: — Length, 1,54 — 2 mm. (the typc-spcciincn, Irom Villefranchc-sur-mcr, 

 measureil 1,93 mm.). It agrees very closely with the type species except with regard to tlie 

 fine pores on the part between the spine-bearing list and the posterior margin of the shell; these 

 are considerably fewer than in the type species, about four to six near each broad pore, fig. 1. 



First antenna: — The f-bristle has five, the c- and g-bristles six sensorial filaments. 



yi a n d i b 1 e: — The second protopodite joint has dorsally only the two distal 

 bristles that are characteristic of the Asteropidae; on the other hand there are no bristles at all 

 at the middle of the dorsal side. E n d o p o d i t e: Second joint: The female examined had 

 the following number of cleaning bristles: The right mandible had six bristles in a distinct 

 lower row, one bristle close to the main bristle b and one obliquely distally inside the last- 

 mentioned one. The left mandible had six bristles in a distinct lower row, one between the 

 main bristles b and c and one somewhat inside the main bri.stle b. 



The sixth limb has 27 — 28 posterior ventral bristles. 



In other respects it agrees with the type species. 



Male: — See G. W. MUller loc. cit. 



Synnnijmy. Remarks: — In order to make a verificatory examination I applied to Professor 



G. W. MOller for a mature female of the species from the Bay of Naples, which he has dealt 

 with on p. 219 of his large Ostracod monograph, 1894, under the name of Cylindroleheris oblonga. 

 Professor MCller kindly sent me a Naples specimen of this form. Although unfortunately this 

 specimen was not mature — it was a male in the last larval stage — yet my synonymization given 

 above, the result of a careful examination of this specimen, may be considered, if not as abso- 

 lutely certain, at least as being fairly certain. The only character in which the Naples specimen 

 differed from the form investigated by me was that its right mandible had three, not two, dwarf 

 bristles on the backward pointing process on the second protopodite joint. As all the other 

 species in this group of forms — A. Grimaldi, norvegica and oculata — have two dwarf bristles 

 on this process it does not seem impossible that we are concerned here with an accidental variation 

 At any rate it did not seem to me that this character ought to prevent this synonymization. 



It foUows from this synonymization that 6. W. Mt'LLER's description and figures of this 

 species are in a number of respects — even in the characters of the genus — somewhat incorrect. 

 The mistakes will be seen by a comparison with the information I have given above. 



G. W. MULLER in his work of 1912, p. 45 includes a species Asterope Mariae (W. Baird). 

 The following forms are synonymized with it: Cypridina Mariae, W. Baird, 1850 c, Cypridina 

 oblonga, E. Grube, 1859, Cylindroleberis Mariae, G. S. BRADY, 1868 b, Copeclmete elongata + ?
