Even if the greyer colour is, as it may be, largely due to 
the specimens being all in the spinous summer coat, this 
subspecies deserves recognition by its shorter tail, shorter 
palatine foramina and smaller teeth. It is the farthest to 
the north-east of the races of R. confucianus.

Tu1s is the second part of the series published so far, the first 
(vol. iii. pt. 1) being on the Fishes by E. R. Waite; and both do 
great credit to their begetters, being both well done and well got up. 
Mr. Hedley describes some 125 species of Mollusca, obtained 
from the twelve dredging-stations on Adelie Land and from Mac- 
quarie Island, including 41 new species and 2 new genera, All 
these new forms are most excellently illustrated, though one could 
wish that the degree of magnification or reduction had been indi- 
cated on the plates, or at least given in their explanations. No 
general deductions are given, all such, we believe, being reserved 
for special treatment when all the branches of zoology have been 
dealt with. Mr. Hedley, however, does point out that ‘ about a 
third of the Mollusca reported from Macquarie Island extend to 
Kerguelen, and some range round the pole to the Falkland Islands 
and New Georgia,” whilst he considers that probably some of the 
forms here described as new will be eventually traced to other 
subantarctic lands.
