OF THE BRITISH SPECIES. 71 



of Lloyd,* by whom it was gathered near the viHage of 

 Borth in Cardigansliire, and by Ray himself near Sheer- 

 ness. Ray has also mentioned the two species or varieties 

 of the fresh-icater sponge as having been found in the river 

 Yare near Nor^\dch by Newton ;t and by Mr Bobart :|: 

 in the " Thames by Swythens Wyars near Oxford ;" and 

 the same had been noticed growing in the Cam, between 

 Cambridge and Chesterton, by Morton, — the historian of 

 the Natural History of Northamptonshire. Dillenius, in 

 his edition of the " Synopsis," has not added to the list of 

 sponges, for his " Spongia informis durior" appears to be 

 identical with the Halichondria panicea already mentioned. § 

 Ellis has described only two species in his English Co- 

 rallines ; but in the " Zoophytes," edited by Solander, se- 

 ven are very clearly defined. These are are 1. Sp. ocu- 

 lata, 2. cristata, 3. stuposa, 4. urens, 5. palmata, 6. hotry- 

 oides, and 7. coronata : — all of M^hich, with the important 

 exceptions of 6 and 7, had been previously ascertained to 

 be natives, for the oculata, is synonymous with the ramosa 

 of Ray, and cristata and urens are merely varieties or states 

 of his crumb-of -bread sponge. Turton, in his translation of 

 the " System of Nature, 1806," enumerates eleven British 

 species without, at the same time, having made one single 

 real addition, for his Spongia tomentosa and panicea are but

 cessor as Superintendant of the Oxford Botanical Garden. Ho died in 

 December 1719. See Pulteney's Slictches, i. p. 312; and Richardson's 

 Correspondence, p. 9-11. 



§ The " Spongia parva sordidior ex ostrearum concliis" of Pliikenet ; 

 and the Pseudo-Spongiacoralloidesof Doody, (Syn. p. 29 and 30), I have 

 not been able to identify.
