PORIFEEA OF THE L.M.B.C. DISTRICT. 233 



Ascetta coriacea had previously been recorded from Port 

 Erin and Holyhead, and I collected again great quantities 

 of it at Fleshwick Bay, near Port Erin, Easter, 1890. 

 Ascaltis botryoides, Fleming. 



A number of specimens of this form were obtained in 

 Fleshwick Bay, near Port Erin, on the " Hyaena" expedi- 

 tion of Easter, 1889. I found them in a shallow pool just 

 beyond the entrance of a long and narrow cave, where I 

 collected some again at Easter, 1890. The level of the pool 

 was near high-water mark (!). 



Mr. Higgin records this species from Holyhead. 

 Ascaltis coiitorta, Bowerbank. 



Leucosolenia contorta, B., Brit. Spong., vol. ii., p. 29 ; vol. iii., pi. iii. 

 Leucosolenia contorta, Carter, Midland jSTaturalist, vol. iii., p. 195. 



A few small specimens have been found for the first time 

 in our district by Mr. Herbert C. Chadwick, near Beau- 

 maris, August, 1889, and subsequently I found it myself 

 at Hilbre Island, March, 1890. Bowerbank records it 

 from Guernsey, Scarborough (?), and from the Guliot Caves, 

 Sark. 

 Ascortis larunosa, Johnston. 



Grantia lacunnsa, Johnston. 

 Leucosolenia lacunosa, Bowerbank. 



I refer to this species a few specimens which were 

 dredged on the '' Hygena " expedition of May 25th, 1890, 

 in Penrhos Bay, off Ehoscolyn Beacon, and off Porth 

 Dafarth, where they w^ere found sticking to Zoophytes. 



The presence of oxeote spicules in the stalk-like portion 

 of these specimens shows that they belong to this species 

 and not to Ascetta primordkiUs, Hkl., some varieties (espe- 

 cially N ardor us primordiaUs)* of which they resemble very 

 closely. For figures and descriptions see Bowerbank!
