OPHELIIDAE. 
Ammotrypane aulogaster, Rathke.—Occasional in 
the dredge. The only specimen I have seen came from 
near Bradda Head. 
MALDANIDAE. 
Prazilla gracilis, Sars.—Recorded in the 11th 
Annual Report as dredged along with Panthalis. 
ARENICOLIDAE. 
Arenicola marina, L.—Common everywhere in the 
sand. 
Arenicola ecaudata, Johnst.—Not so common as the 
last. 
Arenicola grubei, Cpde.—This and the last species 
occur both at Port Erin and at Bay ny Carrickey. See 
the report by Gamble and Ashworth in llth Annual 
Report. 
CHLORHAEMIDAE. 
*Siphonostoma (Flabelligera) affinis, Sars.—One 
specimen, dredged on the Houlth Bank. 
SABELLIDAE. 
Sabella pavonia, Sav.—Recorded by Hornell. Occurs 
occasionally in the dredge, but is not common. 
*Dasychone bombyzx, Dalyell, var. herdmani, 
Hornell.—Dredged on the Houlth Bank. This is the 
form described by Hornell as D. herdmani. Except the 
spathulate form of the dorsal appendages, with their 
frilled margins, I can find no points of distinction from 
the ordinary D. bombyzx. I therefore prefer to regard 
this as a variety rather than as a distinct species.
