(?) AutolytuB prolifer (0. F. Miiller). 



1908. Mcintosh. Tom. cit, p. 21.'.. 



Malahide Inlet, 17, y\, '08. Dredge, 2 fms. 



One specimen, a female bud, was found, which agreed exactly in 

 colouring with that figured by Mcintosh (;tom. cit., pi. xlLx, fig. 7). Its 

 colouring is very like that of the nurse-stock of A. pictus; and I am inclined 

 to think that it belongs to the latter species.
