 ficles not lurrounding the flem in any regular feries, 

 and in their ihape. Height, from one to three inches. 

 Young Ihoots clofely imbricated to their bafe, but 

 older ones often naked : the fmaller branches, which 

 proceed from a main ftem, have the veficles placed 

 bifarioufly, but at their apex they refume the im- 

 bricated form.

Obf. This minute coralline differs confiderably from 

 its Britifli congeners in habit, but agrees with them 

 in texture. Its origin is a fimple cylindrical ftem, 

 affixed at its bafe, which is "a little dilated to the 

 fl:ems of the Conferva : it foon, however, lofes this 

 form, and very abruptly becomes dilated into a fan- 

 Ifiaped compreffed body, from which proceed eight 

 rays. Tliefe rays, when examined under the firft 

 magnifier of Ellis's microfcope, appear compofed of 

 equal and perfedlly cylindrical tubes. In fome I 

 obferved a deep crimfon fpot, which was probably 

 a dead or torpid polype.
