Professor Heller kindly sent me cotypes of some of the species described 

 by him soon after his work was published. Among them was L. appendi- 

 culata, which agrees in every particular with Busk's L. marsupiata. The 

 species is a strongly characterised form, the stout oral spines with their black 

 bases, and the outermost pair forked (but not trifid as represented by Heller) ; 

 the long black vibracula, which directed upwards overtop the semiglobose 

 imperforate ooecium, and the basal portion of which bears a complete bar ; 

 the rough surface of the zooecium, and the pore set in a distinct cup, which 

 is either complete below the oral lip, or incomplete, being united with the 

 sides of the oral opening, are characters very different from any other specier? 

 known to me. Busk's figure is very good. There are sometimes no 

 vibracula, at others two to every cell. 



The species is not rare off Madeira in 40-70 fathoms, usually in company 

 with such species as Onychocella angidosa and Lepralia peristomata.

A few specimens in about 40 fathoms. Hincks, as above, was the first to 

 record it as a recent species. To his description may be added that there are 

 eight mouth-spines, and that six of these are still visible in front of the 

 ooecium, which is usually girdled with two ribs. I give illustrations from a 

 living and from a dead example. 



MiCROPORELLA CORONATA (Audouin). (PI. 39. fig. 4.) 



1826, Flustra coronata, Audouin, Savigny's Egypte, pi, 9. fig, 6.

Zooecia moderately tumid, surface granular and punctate ; a crescentic 

 pore a little below the lip ; two vibracula of moderate length, held stiflfly, 

 situated far forwards on a line with the pore or even in advance of this close
