M. Marion indicates further a series of Desmophyllum crista- 

 galli, and two new species of Caryo])liyllians — one that must 

 be ranged among the true Gary op /ri/l lice, while the other takes 

 its place in the group of the Bathycyathi. The Hydroids, 

 everywhere feebly represented, belong to northern forms 

 [Dicoryne flexuosa, Sars, hophoUenia tenuis, Sars). A 

 species of Aylaophenia {A. FoUnii) is new. 



Among the Vermes we may indicate some fine Sipuncu- 

 lians belonging to North-Atlantic types ( Ocnesoma Steenstrupi, 

 Sipunculus norvegicus). A Phascolion and an Aspidosiphon 

 will have to be carefully compared with the species recently 

 described by the naturalists of Christiania. 



The Chietopod Annelids are not rare. One of the most 

 remarkable is a large blind Eunice {Eunice amphihelite, 

 Marion) found in a parchment-like tube, around which was 

 developed a fine polypary of Amphihelia oculata. We may 

 mention further a fine Aricia allied to A. Kupferi, Ehl., a 

 Euphrosyne, a Terehella, an Amphoretian, a Nereis, species 

 of Polynoe, and a Vermilia, the tube of which is attached to 

 Lophoiielioi. 



All the Alcyonaria possess great interest. There are : — 

 1. Funiculina quadrangularis, Pall. ; 2. Pennatida aculeata, 

 Kor. & Dan. ; 3. Kophohelemnon stelliferum, Miiller ; 4. Um- 

 hellula amhigua, Marion*, a very curious species, which closely 

 approaches U. grandijiora, Kijll., from Kerguelen's Land ; 

 5. Plexaura desiderata, Marion, found at 1094 metres, and not 

 yet described ; 6. Muricea paucituherctdata, Marion ; 7. Isis 

 {Mopsea) elongata, Esper ; 8. Two very curious Gorgonidaj, 

 the intermediate characters of which are very remarkable and 

 which belong to new types. 



The Echinodermata are ver}^ numerous ; and among these 

 animals the Stellerida possess a very marked predominance. 

 The dredge brought up numerous fragments of Brisinga, and 

 even a perfect example of this fine sea-star. M. Perrier has 

 ascertained that the arms undergo metamorjihoses with age j 

 and their study proves that the genus Ilymenodiscus is inti- 

 mately related to the Brisingce. 



Among the new species of Asteriidai we may indicate two 

 Pedicellasteres (one with five, the other with six arms), and a 

 very remarkable small sea-star which must form a genus 

 under the name of Iloplaster spinosus, I'errier. The Oijhiu- 



* This species differs from Umhellula Tli(»)i,s(>Hi b^- having its sareo- 

 soma destitute of calcareous sclerites. The ptilyps are grouped, without 

 any bilateral arraugemeut, upou a large iutlatit)n : there is no rhachis. 

 The axis at its upper extremity forms a very wide and twisted lamiua, so 

 as to throw out all the polj-ps in a pejident bunch.
