was common also in the ' Challenger ' dredgings, but that be had 

 not hitherto found any satisfactory description or figure of it. 



TuEBO sAisr&uiisrEUS, Linne, 

 T. sanguineus, L. S. N. ed, xii. p. 1235, 



Var. pallida. Smaller, yellowish white with a red apex or tip, and 

 having the spiral striae rather slighter and more numerous. 



Hah. Korea, 2-4 fathoms ; several specimens. Throughout the 

 Mediterranean, from a few fathoms to 120. 



Fossil. Newer Tertiaries of Nice and Southern Italy. 

 The colour of Mediterranean specimens varies from blood-red 

 to yellowish-brown ; but the apex is always red. Such specimens 

 likewise differ in respect of the number and comparative stoutness 

 of the spiral striae. 



The umbilicus is perforated in the young only. It is probable 

 that Linne may have included Trochus Adansoni, and especially 

 the variety turbino'ides, in his description of Turbo sanguineus, by 

 saying " umbilicus aliis perforatus, aliis nequaquam." 



It is the Turbo purpureus of Eisso and T. coccineus of 

 Deshayes.

Mab. Korea. Oceanic and gregarious in all southern latitudes. 



Weinkaufi" mistook this for the Spinalis Jeffreysi of Forbes and 

 Hanley, which belongs to a difi'erent genus. 



Of the above named fourteen species, six (viz. Anomia ephip- 

 pium, Pecfen similis, Lepton sulcatulum, Axinus flexuosus, Panopea 

 plicata, and Turbo sanguineus") are here noticed for the first time 

 as living in the North Pacific as well as in the North Atlantic ; 

 Nucinella ovalis and Kellia pumila, which had been regarded as 

 extinct, the former not only specifically but generically, are now 

 recorded as recent : the other six species (viz. Terebratwla caput- 

 serpentis, Crenella decussata, Lascea rubra, Saxicava rugosa, Punc- 

 turella noachina, and Embolus rostralis') were already known to in- 

 habit both oceans. No less than nine out of these fourteen species 

 are Coralline-Crag fossils : they are Terebratula caput-serpentis, 

 Anomia epMppium, Pecten similis, Nucinella ovalis, Lascea rubra, 

 Kellia pumila, Axinus flexuosus, Panopea plicata, and Saxicava 

 rugosa.
