314 Miscellaneous. 



annelids of the oceanic coasts of France, and eight of these likewise 

 exist in the Black Sea : — 



*Staurocephalus rubrovittatus. *Syllis gracilis. 



Eunice Ilarassii. variegata. 



Marphysa sanguinea. Odontosyllis gibba. 



*Lysidice ninetta. *Syllides pulliger. 



Ouuphis tubicola. *Spba3rosyllis bystrix. 



Nematonereis unicornis. *Eteone picta. 



Arabella quadristriata. Heterocirrus saxicola. 



*Nereis cultrifera. Sabella reniformis. 



* Dumerilii. 



We do not wish, however, to indicate these faunal relations except 

 in a provisional manner ; for it is probable that future researches will 

 considerably modify their significance. 



The great family Eunicea has furnished us with a new species of 

 Marphysa (M. fallax), well characterized by the composite seta? with 

 bidentate uncini existing in the inferior bundle, and by the form of 

 the parts of the maxillary apparatus. In its general aspect this 

 Marphysa resembles Lysidice ninetta. 



The Syllidea are excessively abundant and very varied. We have 

 ascertained the existence of a new species of the genus Anoplosyllis, 

 very distinct from that of the Bay of Naples by the arrangement of 

 the dorsal appendages, which are articulated from the third setigerous 

 segment. Syllis torquata, sp. nov., bears in the anterior region a 

 large transverse blackish band, which is not figured in any annelid 

 of the same group. Lastly, EusylUs lamelligera, sp. nov., and Auto- 

 lytus ornatus, sp. nov., possess still more important peculiarities of 

 structure. It may be remarked that the genus EusyUis, proposed 

 by Malmgren for some worms from Spitzbergen, had not hitherto 

 been indicated in the Mediterranean. 



In the family Hesionea I have to cite a very curious undescribed 

 type, Magolia perarmata, of which the trunk is armed with two 

 maxillaries and a style, whilst the anterior region of the body 

 presents two antenna?, two palpi, and twelve tentacular cirri. The 

 new genus Gyptis, with an unarmed proboscis, appears to be allied to 

 the O.vydromi ; but this latter group, w T hich is very badly determined, 

 remains still unsettled. 



It is undoubtedly near the Hesionea and at the head of the Phyl- 

 lodocea that we must place the annelid that we name Lacydonia 

 miranda, the characters of which may be given as follows : — 



Head furnished with four small anterior appendages representing 

 two palpi and two antenna? ; buccal ring provided with a single pair 

 of tentacular cirri ; dorsal and ventral cirri pinniform : feet of the 

 first three segments setigerous and uniramosc ; feet of the follow 7 ing 

 segments furnished with a dorsal ramus of simple seta? and a ventral 

 ramus of composite seta? : trunk unarmed, comparatively short, and 

 situated between two very complicated tubular secretory apparatus, 

 no doubt representing the lateral tubes of the Hydrophani. 



In the Gulf of Marseilles, among the rolled pebbles of the shore 

 of Ratonneau, we have found the interesting Saccocirrus of the 

 Black Sea. The sexes are separate ; but the reproductive apparatus 

 presents perfectly exceptional peculiarities. In the male the testes
