Mr, T. Whitelegge on Australian Polyzoa. 13 



II. — Notes on some Australian Polyzoa. 

 By T. Whitelegge *. 



In the British Museum Catalogue of Marine Polyzoa, part ii. 

 (1854), the late Mr. Busk, F.R.IS., described two species of 

 Poljzoa from the Philippine Islands, which he referred to the 

 genus LunuliteSj at the same time remarking that they were 

 " curious forms and would appear to constitute a peculiar 

 group." In the years 1879, 1880, and 1881 the Rev. J. E. 

 Tenison- Woods, Mr. W. A. Has well, and the Rev. T. 

 Hincks published papers describing several species which 

 are closely allied to those described by Mr. Busk. Tlie 

 various species have been assigned to four or five genera. I 

 intend in this paper to show that the undermentioned species 

 form a very distinct group, having little in common with 

 those with which they have usually been associated except 

 habit or form : — 



Lunulites philippinensis^ Busk. 



cancellatay Busk. 



Cwpularia crassa, Tenison-Woods. 

 Conescharellina depressa, Has well. 

 Lunulites angulopora, Tenison-Woods. 

 Conescharellina conica^ Haswell. 

 Lunulites incisa, Hincks. 

 Eschara umhonatay Haswell. 

 Flabellopora elegansl^ d'Orb. 



Mr. A. W. Waters, in a paper " On some Fossil Polyzoa 

 from New Zealand " (Quart. Journ. Geol. Soc. Feb. 1887, 

 p. 71), states that he had received from New South Wales 

 recent specimens of the last-named species, " which is either 

 Lunulites cancellata, Busk, or very closely allied to it." 



The published descriptions and figures show that the species 

 in the above list have not as yet been fairly understood, nor 

 has the operculum-bearing aperture or the very exceptional 

 method of growth been fully described. Nearly all the 

 figures representing zocecial characters are the wrong side up, 

 whilst the peristomial orifice has been described as the true 

 oral aperture, and a special pore situated above the mouth 

 has been mistaken for the sinus in the lower lip. 



Mr. Woods figures the oral aperture in Gupularia crassa^
