Having, upon further searcli, met with a tolerably good 

 specimen of this species, which is described in the last part of 

 " Zoophytology" (vol. viii, p. 280), I now give a figure of it> 

 sufficient to facilitate its recognition. 



Fam. 2. Membranipokid^. 



Gen. 2. Membranipora. Blain, S. 



1. M. irregularis, D'Orb. PI. XXXIII, fig. 3. 



Cellulis distantibus subovalibm, inesqualibiis irregulariter dispositis; mar- 

 gine granulatOy inermi ; aviculariis (?) 



Cells distant, mostly oval or suborbicular, very irregular in size, and placed 

 irregularly ; margin granular, wholly unarmed ; no avicularia. 



M, irregularis, D'Orbig., (Am. Merid., pi. viii, fig. 6). 

 (?) M. simplex, D'Orbigny (ib., figs. 7 — 9).

 (?) Flustra distans, Hassall ; Johnston ; W. Thompson. 



There are two or three species with which the present 

 might be confounded, and, in fact, from which its absolute 

 distinctness is by no means certain. 



These are : 



1. M. imbellis, Hincks. 



2. M. Lacroixii, Aud. 



3. M. simpleWi D'Orb.
