Fam. SaUcomariada. Busk. 



Gen. Onchopora, Busk. ('Quart. Journ. Micr. So.,' vol. iii, 

 p. 320.) 



1. 0. Smclairii, n. sp. Busk. PL XV, figs. 1, 2, 3. 

 Cells ovate, veutricose, attenuated at the bottom, slightly keeled in front, 

 the upper part of which is occupied by a scutiform area, having in the 

 centre a lunate pore ; mouth large, sub-orbicular, the lower lip nearly 

 straight ; surface smooth ; ovicell raised, globose, large, M'ith a promiuent 

 central umbo, from which costse radiate on the sides and summit. 



Hab. New Zealand, Dr. Sinclair., Dr. Lyall. 



The characters of tlie genus Oncliopora will require to be 

 altered to admit the present form, which is obviously too 

 closely allied with those previously included in it, and espe- 

 cially with O. mutica, to allow of their being separated. The 

 alteration will consist in the omission of the last part of the 

 character given as above, or that referring to the ovicell, 

 which in the present species is very large and peculiarly 

 marked. 



The polyzoary of the present species, which has something 

 of the habit of a Salicornaria, is constituted of cylindrical 

 branches of various lengths and usually dividing dichoto- 

 mously. The whole forms a more or less dense rounded 

 tuft. 



2. L?j)ralia, Johnst. 



1. L. thyreophora, n. sp. Busk. PI. XV, figs. 4, 5. 



Cells ovate, upper half in front occupied by a scutiform area, in the 

 centre of which is a lunate pore, and on either side a single row of punctures (?) 

 which also extends across the front of the cell immediately below the 

 mouth, which is rouuded above with a straight lower lip ; ovicell lofty, 

 rounded, faintly punctated. 



liab. New Zealand, Dr. Sinclair. 



This Lepralia, which is parasitic upon O. Sinclairii, in some 

 respects resembles L. Mahisii (B. M. Cat., pi. 103), differing 

 from it, however, in its having a distinct scutiform area on 

 the front of the cell, and in the arrangement of the apparent 

 perforations or puncta, which exist only around the margin 

 of the scutiform area and across the upper border of the cell, 

 whilst in L. Malusii the entire front of the cell, except in the 

 centre, is punctated.
