P. 930. Lyonsia formosa. Off West coast of Africa (' Talisman ' 

 Exp.); 452-731 fins. 



P. 932. Pecchiolia subquadrata. Off Sahara (' Talisman ' Exp.) ; 

 681-1261 fins. I overlooked other 'Porcnpine' 

 Stations for this species, viz. 1869: St. 16, 17. 

 These specimens are larger than the size given in the 

 description. 

 „ Pecchiolia. insculpta. Off West coast of Africa and 

 Azores ('Talisman' Exp.); 478-681 fins. Very 

 large and fine specimens. 



P. 933. Pecchiolia angulata. Off Marocco and Sahara (' Talis- 

 man ' Exp.) ; 617-781 fms. An extraordinarily 

 large valve from the latter station. 

 „ Pecchiolia acuticostata. Off Marocco (' Talisman ' 

 Exp.) ; 650 fms. A large valve. 



P. 937. Neoera subtorta. Fossil. Post- tertiary : Garvel Park, 

 Greenock {Scott and Steel). 



P. 938. Necera cuspidata. Off Marocco ('Talisman' Exp.);

 „ Necera gracilis. Off Marocco (' Talisman ' Exp.) ;

P. 940. Necera depressa. Off Sahara and the West coast of 

 Africa ('Talisman' Exp.): 452-1261 fms.

P. 941. Necera contracta. Off Marocco and Azores ('Talisman' 

 Exp.); 1192-lti22 fms. Mr. Dall now refers this 

 species to his N. limatula, described in the Bulletin of 

 the Museum of Comparative Zoology, vol. ix. No. 2, 

 p. 112. His report is dated December 5, 1881. 

 But in that description he says that his species is 

 clearly not one of mine. He has since had an 

 opportunity of comparing the types of both species. 

 „ Necera semistrigosa. Referred by Mr. Dall to his N. 

 lamellifera in the same publication. My publication 

 is dated Nov. 29, 1881. 



P. 942. Necera circinata. Off Marocco (' Talisman ' Exp.) ;
