It may be well, as 1 am noticing this genus, to refer also 

 to this other northern species. K. arborescens has the zoariura 

 attached not by one chitinous tube, but by many, and these 

 are short ; the zoarium is more calcareous than in K. Smitti^ 

 all the branches arch over and bend downwards, like an 

 opened umbrella *, while the stems bear the proportionate 

 height of its handle. The zooecia are on the upper surface of 

 the branches ; they have their backs marked with curved 

 lines, as represented by Dan. & Kor. On the front there is 

 no spine-point at the upper outer angle, but, instead, this 

 angle is the point for the attachment of the avicularium, 

 which thus occupies a different position from that in the three 

 other known species ; the avicularium is much shorter and 

 more tumid — Dan. & Kor. correctly say " it resembles an 

 eagle's head in shape," — with the crown much arched. 



The points I have mentioned distinguish this species from 

 A', pocilhttn, Busk, of the ' Challenger ' Expedition, as well 

 as from the species here previously described. S])ecimens 

 examined are from the Gulf of St. Lawrence {Mr. Whiteaoes) 

 and Kara Sea, ' Dijmphna' Expedition [Copenhagen Museum). 

 This last specimen has ooecia, which have not previously been 

 observed. They are semiglobose and similar in character to 

 those of the other species.

* Busk is mistaken in supposing' [oide ' Challenger' Report, p. 45) that 

 Smitt has represented his specimen " the wrong way up in his tigiu'e." 



t Busk, in ' Challenger ' Report, Cheilostoniata, 1884, makes Metn- 

 branipora Flemingii the type of Aviphlblestrum. In order to understand 

 this we must refer to his Cat. Marine Polyzoa in Brit. Mus., Cheilosto- 

 mata, p. 58, where, in describing M. Flemiw/ii, he makes Flustra meinbra- 

 tiacea, Abildg., a synonym. It is strange how he can have fallen into 

 such a mistake, for there is nothing in Abildgaard's description or figure 

 applicable to M. Fkminf/ii. The following words are important in that 

 author's description, which is confirmed by the figure : — " Cellulis mar- 

 gine calcareo cinctis, et membra hyalina tectis. In medio margiuali basis 

 prostat mucro elevatus plus minus elongatus, etc." ''■ What, then, is
