88 Rev. T. Hlncks's Contributions towards a 



(pi. XXV. fig. 2) a subtr I angular space on the front of the 

 ooecium is inclosed by prominent raised lines, whilst in the 

 Madeiran specimen its place is occupied by a smooth, sub- 

 acnniinatc elevation which stretches upward from the oral 

 arch. Such differences in superficial detail have little syste- 

 matic significance.

Microporella decorata^ Reuss (sp.) . 



Syn. Microporella diadema, Mar,Gilli\rav, Prodromus Zool. Victoria, 

 decade iv. p. -iO, pi. xxxvii. fig. 0; Jlincks, " Contributions" &c., 

 Ann. & Mag. Nat. Hist. ser. 5, vol. xv. p. 249, pi. viii. tigs. 3. 



The ooecium is liable to considcvable variation. Compare 

 the figure in Manzoni's ' Bryozoi fossil. Italiani,' pt. ii. pi. i. 

 fig. 6, with JMacGillivray's. " Tiie broad band of vertical 

 beaded lines," which is so marked a feature of the recent 

 form, is represented in the fossil by a line of small nodules 

 round the base of the ooecium, which is not even referred to 

 in the description. 



In the account of M. decorata I have referred to Micro- 

 porella violocea, Johnston (sp.) ; but tiiis species, we now 

 know, should probably be included in the genus Adeona*, 

 Lamouroux, the genus Reptadeonella of the ' Challenger ' 

 Report being quite untenable.

 Lepralia Kirchenpaueri, Heller, var. teres. 



The Madeiran form, which I have legarded as a variety oi 

 Heller's species, Mr. Waters would refer to L. Poissonii^ 

 Audouin. On further consideration I am not disposed to 

 adhere to my iormer o})inion. The shape of the cell, which 

 is much more distinctly given in J\huizoni's figure than in 

 Heller's, is very ])cculiar, and ditfers widely from that which 

 is shown in my figure (' Annals,' ser. 5, vol. vi. pi. ix. figs. 7). 

 A di.stinctivc feature of Heller's species is the ribbed ooecium ; 

 but that of the Madeiran form is of small size and smooth
