74 A MONOGRAPH OF TIIK TEltTTAltY POLTZOA OF VICTORIA. 



WatcM-s fii^im^s this spocios From Moiiiil (i;iml)i('r, rclcrring it to tlic Eiiro})(\in 

 L.foliacca. In liis l^aimsdale paper lie says it may possibly liavo to be specifically 

 se))arated. Jiuli^'iiiL;' IVoiii the descriptions and tlie specimens of L./oUdCoa T have 

 examined, I see no reason foi' rel'eri'ing' it to that sjiecies, and tliend'ore describe^ it 

 as n(>w.

/oniiiim unilaminate, ])rol)ably encrusting. Zoo)cia distinct, rounded, with 

 numerous lai'ge, close, round pores ; thyrostonn^ arched aboA-e, contracted Ixdow, the 

 lower lip sti'aight, a small internal denticle at each angle, and several s])ines on the 

 up])er margin ; a ])ore or depression, seemingly avicularian, on <'acli side of the 

 thyrostome. Posterior surface having the zorecia indistinct, with nunu^rous small 

 perforated tubercles probably for the attachment of i-adical tubes.

The specimen figured does not shew the internal denticles of the thyi'ostonie, 

 l)ut ill andlher they are distinct. The form of the thyrostome and the pr(>sene<> of 

 th(> denticles shew that it should be referred to Lepralia.

Zoarium bilaminate. Zocecia distinct, separated by grooves, the margins 

 occasionally very slightly rais(>d, more or less hexagonal, surface with numerous 

 i-ather small pores; thyrostome large, rounded above, straight below, situated a littl(> 

 below the upper extremity of the zo(eci\im ; peristome slightly thickened.

There may be some doubt as to the i)roper systematic position of this sjiecies. 

 On the whole it seems to me to belong to Lepralia. Waters places it and the last 

 s])ecies, as well as Macpopora c'arkf'i, in Alonoporella, a genus propos(>d by Ilincks 

 for th(> r(>ception of two species fi-om Bass's Straits, M. nod idifera and ]\l. Icp'nla, to 

 which lie subsec^uently added M. olbicans from Singapore and M. Jn-nnuoa from 

 Queen Charlotte Islands. Of tliese M. lepida is clearly a Micropora, while M. albicans 

 should probably go to Cellejiora, where it has already been placed by Waters. 

 M. iindidosa miglit be taken as the type of a genus, with Avhicli, howc^ver, M. hi-iuiucd 

 could scarcely bo associated.

 gularly arranged, concave, with thickened rais(;d margins ; surface with numeioiis
