Lepralia turrita Smitt. (PI. LXXIII. fig. 10.) 



Lepralia turrita Smitt, Floridan Bryozoa, pt. ii. p. 65, pi. xi. 

 figs. 226-228 (1873); Kirkpatrick, Ann. Mag. Nat. Hist. ser. 6, 

 vol. V. p. 16 (1890) ; Thornely, "Mar Poly, of the Indian Ocean," 

 Trans. Linn. Soc, Zool. vol. xv. p. 150 (1912). 



The small specimen from Wasin has four long calcareous 

 spinous processes, irregularly placed round the aperture. One 

 or more of these processes may bear an aviculaxivim at one side 

 near the base, as in the spinous process of H. albirostris Sm, 

 Besides these avicularia there are on the surface of the zoarium 

 numerous small semicircular avicularia, irregularly scattered. 

 The ovicell is not much raised and has an elongate elliptical 

 opening in the front. A specimen of Lepralia turrita in my 

 collection has short blunt processes with similar semicircular 

 avicularia, and the ovicell, which is morei-aised, has a similar wide 

 opening in the front. Perhaps, on account of the different 

 character of the ovicell, it should at least be made a variety, but 

 until more material is available it is allowed to stand. 



The operculum has the sides nearly straight with the proximal 

 edge curved ; there are two muscular dots a little distance from 

 the edge and two articular thickenings ; the width is about 0*2 mm. 

 This opercukim does not correspond with any with which I am 

 acquainted, for though in many respects it is like those of what I 

 should call, in a restricted sense, Lepralia, there is no lateral ridge 

 for the muscular attachment, which is not close to the border. 



In the British Museum there is a specimen marked turrita, 

 which is Holoporella, and it seems as if there were more than one 

 with a series of calcareous processes round the oral aperture. 

 What Ridley and what I called L. turrita may each have to be 

 placed elsewhere.

Lepralia wasinensis, sp. n. (Text- fig. 81.) 



A small piece with only seven zocecia was found on re-examin- 

 ing some material, when the paper was almost completed. Only 

 the calcareous part remains, which was probably bilaminate, but 

 this cannot be stated with certainty. The zooeeia have the sides 

 straight and the distal end somewhat rounded, with thick borders 

 to the zooeeia. The oral aperture is subrotund with a wide 

 curve on the distal end surrounded by a thick band. The frontal
