XVII.—ON SOME OF THE MOLLUSCA PROCURED DURING 
THE ARCTIC EXPEDITION OF THE ‘FOX’ IN 1858 
AND 1859, sy J. GWYN JEFFREYS, u.p., rns. 
[Read November 18, 1878.1 
When I attended the last Meeting of the British Association at 
Dublin I took the opportunity of examining a collection of Arctic 
shells which had been made by Dr. David Walker, the Surgeon 
and Naturalist to the ‘Fox’ Expedition, and deposited in the 
Museum of Science and Art. This list was published in the 
Journal of the Royal Dublin Society, Volume 8, pages 70 to 72. 
Dr. Carte, the excellent Director of the Museum, kindly assisted 
me in the examination. 
Having had some experience, personal and otherwise, in the 
collection and investigation of Arctic Mollusca, I thought a few 
notes might be useful with respect to the identification of the 
species named in Dr. Walker’s list. Without such identification 
conchologists might be misled by some of the recorded names, and 
our knowledge of geographical distribution would be perplexed. 
I hope on some future occasion to examine the remainder of 
the collection, which is in the Queen’s College, Belfast. 
The names of species, localities, and depths, which follow within 
inverted commas, are extracted from Dr. Walker’s list of specimens 
deposited in the Dublin Museum of Science and Art. 
“ BucciNnuM HyDROPHANUM (Hancock), 15 fathoms, Port Kennedy.” 
There is no specimen thus named ; but one marked “Buccinum 
cyanewm, Crimson Cliffs,” is the young of B. hydrophanum, 
Hane. 
“‘ BuccINUM TENEBROSUM (Hancock). Godhavn, 10 to 20 fathoms.” 
No specimen thus named. JB. tenebroswm, Hane.,is B. Gren- 
landicum, Chemnitz. 
“ Buccrnum cruiaTum (Hancock). Port Kennedy, 10 fathoms.” 
Hancock never described nor named any such species. The 
specimen thus marked is B. Grenlandicum, var sericata, which 
latter name is that of Hancock’s species. 
“ Buccinum piicosum (Hancock), Melyille Bay, 100 fathoms.” 
No such species ; nor did Hancock describe or name B. plicoswm. 
There is a young specimen of B. tenue, Gray, without name, 
which may have been intended.
