LKOI'.KANCHIA'TA, M. I)e Blainville's name for his fifth 

 ordrr of hit second Motion of hii aeooud sub-class (Paracci'haloiihora 

 Monoica). 



M. Rang, who has illustrated the anatomy of some of the familiei, 

 makes the .\*cleobranc/ai<i, in hie arrangement, the first order ( 

 t'uvier's class (iatteropoda, and comprises under it some of the llttero- 

 poda of Lamarck and the family I'terotraoboee of Do Frfruttac. 



The following character of the order is given by M. Kiuig: 



Auimal furnished with a foot compressed into the form of n fin, 

 with an aoetabulum or sucker (ventouse) on its superior bordn-. 

 Branch!*) pectinated. Both sexes comprised in the same individual. 



Often a shell, which is spiral, has a very largo aperture, and ia 

 vitreous and very fragile. 



An operculum sometime!. 



M. Kang observes that the Molluscs which ho had already, in au 

 anatomical memoir on the genus Atlanta, proposed to assemble under 

 the name of Xucltobranthiala, borrowed from M. Do Itlninvillc, are all 

 pelagic animals which are often met with on the surface of the sea in 

 calm weather, swimming in an inverted position by the aid of their 

 foot, which is compressed into a fin. They never creep, but they have 

 the power of fixing themselves (to floating bodies only) by spreading 

 upon them the sucker of their ventral fin, and at the same moment 

 making a vacuum. The shells are very much sought after iu collections 

 on account of their extreme rarity. 



Two families, according to M. Hang's arrangement, constitute tho 

 order A'ucfcofrruncAirto. 



1. f iroliJa; (Pterotracho'es, Fdrruissac; Nedopoda, Blainvillc; 

 Wiic/im, I .at mile). 



Animal elongated, straight, and horizontal ; one or more fins ; 

 branchuo forming, with the other viscera, a nucleus on the dorsal pnrt. 



Shell sometime* present, and when it is, incapable of containing 

 more than a very small part of the amimaL 



Firota(flerolraekea, Korsk.; J-'iruluvla and Sayiltlla, Lee.). Animal 

 very much elongated, gelatinous and transparent, terminated behind liy 

 a tail more or leu long and pointed ; mouth situated at the exl r 

 of a probooU, and including an apparatus proper for mastication (F). 

 No tentacle*, or only two tentacular nidiim-ntn carrying the eyes at 

 their external base ; one or more fins ; nucleus exposed, protected only 

 by a membrane, and always situated below and li. hind ti, \.nii d 

 flu ; termination of the intestinal canal and of the organs of gem i 

 in a tubercle on the right aide. 



No shell (lUng.) 



The finlff are very common animals iu tho seas of tho wait 

 temperate cones, and aro remarkable for their extreme transparency , 

 which is often interrupted by golden spot*.

The oilier genera in this family are Carinaria [CARINAIIIA], and 



2. Atlanti<l,i. 



Animal furnished with a well-developed shell, into which it can 

 retire; gills contained in a dorsal mouth-cavity ; lingual teeth 

 to (.'an'min'a. The shell symmetrical, discoidal, sometimes closed by 

 an operculum. 



The following genera belong to this family :
