Mr. H. J. Carter on neiv species o/Euglena. 17 



distinguishing characters between Astasia limpida and Euglena 

 which I have given at the commencement, is a mistake. For 

 the purpose, therefore, of further emendation, I would also take 

 away these two genera from the Euglenians, and, transferring 

 Ehrenberg's name of '^ Astasiese'^ to them, as well as his genus 

 " Astasia/' thus make a new family, which I know to have several 

 forms so like the different species of Euglena, that they might 

 be viewed as the Euglen(2 of the animal kingdom, without corl-i 

 founding them with the true -EM^Zew^e^^wiiich evideiitly Jaelong; 

 to the vegetable kingdom. Ijooi'ioqijcij o<5 ex xv^v,xN\?,k '^,w^^Y^\^

N /Having during the past year met with two freshwater species 

 oh Euglena which appear to me to be undescribed^I hayenaiped 

 and characterized them as follows : — ^^\iK ot bailifi ^hfioxi 



Short, thick, fusiform, obtuse, of a rich green colour, provided 

 with a long, delicate, single cilium, which projects from a 

 5;; slightly bilabiate anterior extremity, a little behind which is 

 ■'the eye-spot, attached to the contracting vesicle. Nucleus 

 • central, situated between the ends of two elongated, refrac- 

 tive, nucleated cells, which extend round the body equatorially. 

 Tailless. Motion during progression oscillatory, and rotating 

 non the longitudinal axis. Length about l-700th, breadth 



about 1-1 100th of an inch.

Short, thick, ovoid, cylindrical, slightly narrowed anteriorly, of 

 a rich green colour; provided with a long delicate cilium, 



'1 which projects from the notch of a slightly bilabiate anterior 

 extremity; a little behind which is the eye-spot, attached to 

 the contracting vesicle. Nucleus central, between the ends of 

 two wide, refractive, nucleated cells, which extend round the 

 body equatorially. Tail adhesive or suctorial (?), short, about 

 one-sixth part of the length of the body. Motion during 

 progression oscillatory, and rotating on the long axis of the 

 body. Length 1-11 00th, breadth l-1800th of an inchnwij'xb

Obs. These two Euglence are remarkable for having that 

 refractive cell or organ which I have called the "glair-cell" 

 equatorial instead of longitudinal, as in Euglena spirogyra, or 

 single, and in the anterior lip, as in Crumenula texta, &c.*
