Description of a new Species 0/ lletepora //'ohi Port Western, 

 Victoria. By R. Kirkpateick. 



Miss E. C. Jelly recently sent to the Natural-History Museum an 

 interesting specimen of Retepora from Port Western, belonging to 

 an undescribed species. I propose to call the species 



Retepora sinuosa, n. sp. 



Zoarium (in the specimen) contorted, with walls nnastomosing to 

 form tubular alveoli ; walls thick ; fenestroe small, ovoid, smaller 

 than the trabecuho ; zooecia rhomboidal, separated by raised lines 

 starting from middle of margin of 

 each side of orifice ; front surface 

 flat, slightly tuberculated, semi- 

 hyaline ; orifice almost figure-of- 

 8-shaped, the lower and smaller 

 loop forming a wide sinus ; with 

 a beaded rim, except within sinus ; 

 six oral spines, stout, glassy, with 

 imperfect joint at base ; at the 

 foot of each zooecium a medium- 

 sized circular avicularium, occa- 

 sionally a long oval one ; scat- 

 tered about over the cells small 

 oval avicularia ; dorsal surface granular, vibicate, with small circu- 

 lar and oval avicularia, numerous on margins of fenestrto. Ocecia 

 Bubglobose, hyaline, smooth, but marked with irregular raised lines. 



For chitinous appendages see woodcut. 



Loe. Port Western, Victoria. 



The peculiarities of this species consist chiefly in the shape of the 

 orifice and the absence of peristome. The shape of the orifice varies 

 slightly ; generally the sinus is curved ; but in Eome cells the lower 

 border is almost straight, so that the mouth has a shape character- 

 istic of Lepralia.
