Show 1884.] 'LIGHTNING' A N D ' PORCUPINE' EXPEDITIONS. 137 The interstices of the ribs in this species are regularly and striated in the direction of the spire. My largest specimen from tbe 'Porcupine' Expedition is three quarters of an inch in length by nearly half an inch in breadth. I have also from Rasel Amoush fragments of a species which appears to be S.frondicula of Searles Wood. That species is more slender and has more ribs than S. frondosa. As a Pliocene fossil it occurs in the Coralline Crag of Suffolk, the Antwerp Crag, and at Reggio in Calabria. Monterosato gives Palermo and S. Vito for S. frondicula as a recent or living species. 11. SCALARIA TREVELYANA, Leach. S. trevelyana (Leach, MS.), Winch on the Geology of Lindisfarn, in Ann. Phil, new series, iv. p. 434 : B.

Petit therefore named the present species S. clathrus, which is more correct than S. communis according to the recognized laws of nomenclature. 13. SCALARIA GRffiNLANDiCA, Chemnitz.

A living specimen from the last Station (345 fathoms) was nearly two inches long. The animal having been put into boiling water was removed from the shell and kept in spirit of wine; it then gave out a deep violet dye, which did not fade for many years. |
