Onchqpora sinclairii (.'5). 

 Pustulopora proboseidea (2). 

 Salicornaria clavata (3).

 Culella perfunculata (2). 



The preceding list of species from the shallow waters of the Kerguelen Region (List 

 IV.) shows that in the vicinity of these islands of the Southern Indian Ocean, in depths 

 not exceeding 150 fathoms, the Challenger procured representatives of 533 species 

 and varieties of Metazoa belonging to about 325 genera. The proportion of the number 

 of genera relatively to the number of species is here as 1 to l - 64. 



An examination of the list shows that 25 of the species have received no specific 

 names, and there are besides 11 varieties enumerated as well as the species to which 

 they belong ; in addition the list includes 2 species of internal parasites (Entozoa), the dis- 

 tribution of which cannot be discussed along with the other marine organisms. Making 

 these deductions there remain 495 distinct fully-described species the distribution of 

 which may be discussed in detail. 



These 495 species may be divided into those that are known only from thrse 

 dredgings in the neighbourhood of the islands in the Southern Indian Ocean, and those 

 that extend into other regions of the ocean. 



a. Species limited to the shallow -water area of the Kerguelen Region. 



In the first place, we find that there are 326 species (or 61 per cent, of the total 

 number of species and varieties found in these dredgings) which, so far as we know up 

 to the present time, are confined to the area represented by these dredgings. 1 These 

 326 species are distinguished by an asterisk in the list, and very little can be said about 

 them beyond the fact that they are known only from the area represented by these 

 dredgings and from depths not exceeding 150 fathoms. 



LIST IV b. 



We here enumerate the 52 species found at more than one of these Stations or 

 localities, indicating in brackets the number of Stations at which each species was 

 found. It will be observed that only 2 species occurred at all the four localities, 

 while 7 species were each found at three of the Stations, and the remaining 43 species 

 each at two Stations. 



1 Nine of these species have subsequently been recorded from South Georgia, viz., Asterias meridionalis, Ophiogbj\ < 

 hexactis, Lagisca antarctica [= Harmothoe vesiculosa], Nereis kerguelensis, Nymphon brevicaudatum, Litorina [ = Pellm- 

 tOTMio] 8et08a, Jfi m/iarthrv/m setulosvm, Chorizocormus reticulatus, and Colella concreta; there are besides other eight species 

 with a wider distribution (as will be noticed in the succeeding notes) recorded from South Georgia, viz., / 

 antarctica, Hemiaster cavemosus, Serolis septemcarinata, Modiolarcatrape;;ina,Hydrobia [ = Laivilitorina] caliginosa, Troemu 

 (Phot inula) expaiisns, Coblla pudn nrnlata, and Harpagifer bispinis, making altogether seventeen species in our list found 

 since at South Georgia (see PFEFFEB, "Die Niedere Thierwelt ties antarktischen Ufergebietes," Ergebnisse der deuUSm 

 Polar-Expeditionen).
