occurs in Ccllejjora sardonica^ W., Schizoporella hia'perta^ 

 Midi., 8. auriculata, Hass., Lepralia edax, B., Retepora 

 marsiipiata, Sni., var., R. CoucJiii^ H., Porella cervicornisj 

 M.-Edw. In my European specimens of Smittia Landshorovii 

 it is extremely minute, but is somewhat larger in a New 

 Zealand specimen. 



I should feel inclined to consider S. malleolus a variety 

 of 8. Landshorovii and some varieties with the avicularia far 

 down the peristomial aperture have previously been described.

Smittia Napierii^ Waters. (PI. III. figs. 34, 35.) 



Smittia Napieni, Waters, Quart. Jouvn. Geol. Soc. vol. xxxix. p. 438, 

 pi. xii, fig. 14, vol. xliii. p. 69. 



The lyrula is directed inwards, but does not seem to be 

 usually bifid, and at each side of the denticle the peristome is 

 a little raised and forms an apparent sinus ; the ovicells are 

 usually somewhat immersed, but there is considerable varia- 

 tion in this particular. 



This has small zooecia, and no doubt is closely allied to 

 Smittia [Mucronella] tricusjyis, H., but I still thiuk they are 

 distinct.

 Mucronella dtiplicata, Waters, op. cit. vol. xxxvii. p. 328, pi. xvi. 



fig. 54, and vol. xxxviii. p. 266. 



The Green Point specimen is without ovicells. It differs 

 from the typical form in having punctures in pits generally 

 over the surface, and should perhaps be separated as a variety 

 on this account. 



Smittia signata^ sp. nov. (PI. III. figs. 4-6.) 



Zoarium incrusting. Zooecia separated by a thick raised 

 line, usually rectangular, punctured round the edge. Peri- 

 stomial orifice suborbicular, narrower below, with the peri- 

 stome thick and raised ; on one side of the zooecia almost 

 attached to the peristome there is a lanceolate aviculariura. 

 The oral aperture has a distinct sinus, probably formed by 

 two lateral teeth ; the operculum is thin and is strengthened by 

 a thicker raised line, taking the shape of the mandibles of
