SOIENOPOKA. 85 



Genus SOLENOPORA, Dybowski. 



[Die Chsetetiden der Osbalt. Sil. Form. p. 124, pi. ii. 1877.] 



Soleuopora jurassica, Brown ex Nicholson MS. 



[Geol. Mag. (iv.), vol. i. p. 150, figs. 4-5, 1894.] 



Dr. Alexander Brown ' published an interesting account of the 

 structure of several forms of calcareous organisms from Palaeozoic 

 and Mesozoio rooks, which had been classed by previous writers 

 among the Hydrozoa. He describes a species from the Great 

 Oolite of Chedworth, Gloucestershire, and Maiton, Yorkshire, 

 under the name Solenopora jurassica, Brown ex Nich. MS. As, 

 Dr. Brown has shown, there are good reasons for assigning. 

 Solenopora to the CoralHneae, a family of the Floridese, to which 

 the well-known Lithothamnion and other existing types belong. 



Caulerpa Carruthersi, Murray. 



[Phycolog. Memoirs, pt. i. p. 11, 1892.] 



1888. " Equisetaceous plant," Damon, Geol. Weymouth, pi. xix. fig. 12. 

 1892. Caulerpa Carruthersi, Murray, Phycolog. Mem. pt. i. p. 11, pis. iv.-v. 

 1895. C. Carruthersi, Woodward, Lower Ool. p. 402. 



As I have elsewhere- discussed the nature of the Kimeridge 

 iossils referred to Caulerpa, it is needless to traverse the same 

 ground again. It is, I believe, highly improbable that the 

 specimens represent the remains of an alga. The best specimens 

 have the form of a slender central axis, giving off at fairly regular 

 intervals whorls of short and somewhat clavate branches ; they 

 bear a superficial resemblance to such a recent species as Caulerpa 

 ^actoides, Ag. We must leave these fossils as indeterminable, with 

 the suggestion that they have probably been produced by animal — ' 

 rather than by plant — agency. 



The specimens figured by Mr. Murray are in the Botanical 

 Gallery of the British Museum and in the Museum of Practical
