This is only to be distinguished from C. volubilis by the aid of the 
microscope. The two species frequently grow intermixed, and their 
habit is the same, but the syringa is easily distinguished by its denser 
corneous structure, its cylindrical tubular cells, and the shortness of 
the pedicles which support them. Polypes with 8 filiform equal ten- 
tacula. — Pallas describes a branched variety from the coast of Corn- 
wall, which, however, undoubtedly belongs to C. dumosa. His words 
are — “ Nuper ex Oceano Cornubiam alluente, ubi hsec Sertularia in 
testaceis et Zoophytis omnibus abundat, accepi ramescentem eandem, 
seu vegetantem ; dum tubuli plurimi proprii simul assurgent.es efii- 
ciunt stirpes sponte erectas, ssepe sesqui-pollicares, ramumque unum 
vel alterum exserentes, totas ab imo ad sum mum calyculis tubulifor- 
mibus, sine ordine, quaquaversum muricatae.” 
* * Stem composed of many parallel tubes.

* Dr William Brownrigg, born at High Close Hall, Cumberland, March 24, 
1711 ; graduated M. D. at Leyden in 1737 ; elected F. R. S. in 1742 ; in 1748

Copley medal for the year 1765 ; continued to prosecute with zeal his chemical 
and philosophical experiments, and to enjoy his literary taste, until the period 
of his death, which took place at Ormath waite, January 6, 1 800, aged 88 years.
