Notes . — In the tables most of the doubtful species have been excluded. 
X w or X s signify that the species is found in the northern or southern part of the province indicated by the column. 
X placed “ on a line” means, that only the ocean or land is known, but no definite locality is assigned. 
The above Tables certainly communicate a fairly correct idea of the distribution of 
the Holothurioidea, so far as is at present known, but it must be remembered that great 
parts of the world have not yet been explored, and that every year new forms are found 
on our own coast, proving that our present knowledge of the geographical distribution is 
very incomplete, and does not enable us to speak with any confidence. Considering this, 
as well as the fact that scarcely anything is known about fossil Holothurids, only a few 
general conclusions, which seem to be established, may be mentioned. 
With respect to the arctic and antarctic regions, the observations hitherto made seem 
to establish that not a single species of the Holothurioidea is common to both seas. 
Notwithstanding this the shallow-water fauna of the two regions possesses much the 
same features. Thus the northern forms Cucumaria frondosa, Trochostoma borealis, 
P solus squamatus, P solus fabricii, Holothuria intestinalis, &c., are represented in the 
Antarctic Sea by Cucumaria IcBvigata, Cucumaria crocea, Trochostoma violacea, Psolus 
ephijppifer, Psolus antarcticus, and Holothuria magellani. I have had all these forms 
at my disposal, with the exception of Holothuria magellani, and they appear to be 
distinct from one another, though the distinguishing characters, it must be confessed, 
often seem to be rather inconsiderable and possibly not of specific value. It is, however, 
of importance not to neglect such small characters, which unquestionably have a much 
greater consequence than may be at first supposed. According to my opinion, every 
example proving that the arctic and antarctic shaUow-water faunse are different is of 
value, for I cannot conceive how it is possible that they can have animals which are
