STKES : MOLLUSCA OF " PORCUPINE " EXPEDITIONS. 177 



the "Porcupine" off Portugal in 795-994 fathoms. The three 

 specimens from the locality so labelled I attribute to macra, "Watson. 

 There is also a specimen labelled " No. 55, 1870," which I take to be 

 the Mediterranean specimen to which Jeffreys refers, and which 

 appears to be distinct from macra ; this latter I accept as nodulosa, Jeff., 

 and it is so catalogued in the present paper. The type of this latter 

 species is, however, inaccessible to me. Jeffreys in his MS. also 

 notes nodulosa from the " Travailleur " and " Talisman " Expeditions, 

 but I have not been able to trace the form with any certainty in 

 Locard's work ; may it be Bela holomera, Loc. ?

 Beladecussiiia, var. ovalis, Friele: Kobelt. p 258, pi. Ixxxiv, figs. 15, 16. 



"Porcupine" Expedition, 1869, Station 23« (one apparently live); 

 1870, Station 17. 



Distribution. — Deep water on both sides of the North Atlantic. 



The specimens from the latter station are much more strongly 

 scu'lptured. I have followed the identification of Jeffreys and 

 Mr. Marshall.

Bistrilution. — Various localities in the Mediterranean ; also the 

 Azores. 



According to the authorities cited, as also the Marquis de Montero- 

 sato, the present shell has been erroneously attributed by most workers 

 to Philippi's species.

" Porcupine " Expedition (see note below). 



JDistrihution. — Arctic seas and both sides of the North Atlantic. 



Known also as a Tertiary (?) and Post-Tertiary fossil. In the 

 Museum as from " 89 fathoms, North Atlantic," but I am unable to 

 supply the correct cruise or station number. As has been pointed out 

 by Jeffreys and others, the PI. reticulata of Brown has priority.
