ON THE MOLLUSCA PKOCURED DURING THE " POECUPINE "
EXPEDITIONS, 1869-70. SUPPLEMENTAL NOTES, PART IV.^
By E. R. Sykes, B.A.
Bead IWi May, 1910.
The following pages complete the account of the Gastropods which
were not described by Jeffreys, and in the next part I hope to take up
the work of supplementing the portion already published by him, and
to deal with a number of minute forms which had not been fully
investigated ere his death. The figured specimens are in the British
Museum.
DoNOVANiA LiNEOLATA (Tiberi).
NeacBa Uneolata, Tiberi, Journ. Conchyl., 1868, p. 76, pi. v, fig. 5.
" Porcupine " Expedition, 1870, Adventure Bank, 92 fathoms ;
Station 30.
Two specimens, from Station 30, were separated by Mr. Marshall
with a note that they appeared possibly distinct from I). Uneolata, and
that the Marquis de Monterosato was unable to identify them. I am
inclined to consider them as only a variety of this form. One box
of similar specimens in the Museum bears the Station numbers 26, 27,
28, 28«; their accuracy is doubtful.
