ZOOPHYTOLOGY. 277 



two specimens on shell, which correspond in all respects 

 with Mr. Busk's figure. L. Woodiana must, therefore, take 

 its place as a member of our recent Fauna. 



Fossil. — Coralline Crag (Searles [Food). 

 Recent. — Coast of Antrim ; ? Madeira, /. T. J. 



There is every probability that many more of the Crag 

 forms may be obtained by careful investigation, and those 

 who may have opportunities of dredging, especially in deep 

 water, should be on the look-out for them. Mr. Busk's 

 admirable Monograph, published by the Palaeontographical 

 Society, affords a ready means of identifying the species.* 

 5. Lepralia Landsborovii, Johnston. 



The description of this species in the ' British Zoophytes' 

 was founded on a single specimen, supplied by Dr. Lands- 

 borough, which is preserved in the British Museum. This 

 specimen is old and worn and by no means characteristic, 

 and it is not surprising that Dr. Johnston's diagnosis should 

 have been so imperfect and unsatisfactory. Much difficulty 

 has been experienced in determining what form he had in 

 view, and there has been more than one claimant for the 

 honour of bearing the name. 



In his ' Catalogue,' Mr. Busk has given a very admirable 

 figure (pi. cii, fig. 1) of the veritable L. Landsborovii, but 

 has referred it to L. reticulata. A comparison of the form 

 represented in this figure (which I have procured abun- 

 dantly) with Dr. Johnston's specimen, has satisfied me of 

 their identity. 



The following is an amended description of the species : 



Lepralia Landsborovii, Johnston, Brit. Zooph., 2d edit., p. 310. 



„ „ Busk, Catalogue of Brit. Mus. Polyzoa, 



partii, page 66, plate lxxxvi,fig. 1 (taken 

 from the Brit. Mus. imperfect speci- 

 men) ; plate cii, fig. 1 (referred to L. 

 reticulata). 

 Cells ovate-elongate, separated by raised lines ; surface lustrous, thickly 

 covered with punctures ; mouth circular, a denticle within the lower 

 margin, peristome raised, with a spout-like sinus below, enclosing a small 

 avicularium, with a rounded mandible. Ovicell globular, prominent, 

 punctured. 



* Since the above was written, Mr. Busk has furnished me with speci- 

 mens of a new Madeiran Lepralia, so closely resembling L. Woodiana in 

 all essential characters, that I am strongly inclined to agree with him that 

 the two are identical. Thus is added another link to the already nume- 

 rous ones connecting the southern and western and north-western British 

 Polyzoa, with those belonging to the Mediterranean Fauna, and to that of 

 the Crag.
