Grand Manan (Stimpson) ; and " on stones at low-water, Passamaquoddy 

 Bay, in July " (Gould). Stimpson says that it "difl'ers but slightly from 

 D. repanda, A. and H." 



Onchidoris muricata (Mliller). 



Lamellidoris muricata (Mtiller) G. O. Sars (1878). 

 Onchidoris muricata, Verrill (1882). • 



Accoi'ding to Verrill, "specimens dredged at many localities, in 3 to 21 

 fathoms, from Block Island to Halifax, Nova Scotia, appear to belong to 

 "this species." 



Onchidoris pallida (Stimpson). 



Doris ivdlida (Agassiz M. S.) ; Stimpson (1853) ; and Gould (1870). 

 Onchidoris pallida, Verrill (1870). 



Grand Manan, " oS the northern point of Duck Island, in 25 fathoms 

 gravel " (Stimpson) ; common in the Bay of Fundy (Verrill). 



" This species, if distinct from Doris fusca, Fabricius, and D. diajihana, 

 Alder and Hancock, was first properly described, as well as figured, by 

 Gould in 1870. All that Stimpson had previously said about it was that it 

 is remarkable for the large size of the tubercles of the cloak " (Verrill). 

 G. O. Sars, however, distinctly states that Stimpson's Doris pallida is a 

 synonym of 0. muricata, which he calls Lamellidoris muricata.
