H. ambiguum Br., AiisfUhrl. Beschr., &c., in Mem. Acad. St. Peters- 

 burg, 1838, Pis. 27 and 28. — Origin undetermined. From draw- 

 ings left by Mertens. My son has observed a species of this 

 genus at Port Totvnsend, Straits of Fuca, so closely allied to 

 the H. ambiguum, that I am vmable to distinguish it. I sup- 

 pose, therefore, that Mertens may have seen the species he 

 figured at Sitka, or off that coast. 

 Phacellophora Br., Prodr., 1835.

 figs. 5 and 6. — British Channel: Havre (Peron and LeSueur) ;

The more northern Cyanea capillata differs from the C. 

 Lamarckii in the same manner as our C. versicolor and C. 

 arctica differ from one another. C. lusitanica Per. and LeS. 

 may be a third Euroj^ean species. 



' It vvoulJ seem that Ehrenberg never read p. 23, " Dass nun der vorher beschriebene Falten- 



Gsede's accurate description of Aurelia and Cyanea, krauz Genitalien und die auf demselben befind- 



for he makes him represent the ovaries as a liver lichen Korner Eier sind, davon hat mich folgende 



(Ehrenberg, p. 18), while Gwde distinctly states, Beobachtung uberzeugt., &e."
