Tliis is a recent bryozoon the FhiMra rnembranacea, now com- 

 mon in the Baltic. I.t is not certain that the species described 

 by LöFLiNG is the same.

Lamarck in Hist. Anira. sans vertebres vol. 2, p. 206, 

 gives this coral as Favosites Gotlandicus of LiNN^US, but his 

 own description leaves us in uncertainty as to whether it is the 

 same or not, as he says that the »prismes» are »petits». Com- 

 pared with others they are on the contrary large. Linn^US 

 never named it and never gave any »notse characteristicae» of it; 

 to there is no foundation for a Linnean specific nanie. It belongs 

 to a group of Favosites with larger sized, almost equal polypie- 

 rites, which is also found in the Upper Silurian of Norway 

 and by Quenstedt has been called Favosites maximus. ^) It is 

 nearly related to the North American Favosites favosus. In the 

 great confusion, Avhich prevails as to the Favositid^e, I think it 

 best, for the present at least, to regavd this fossil, so common in 

 the oldest strata of Gotland as a variety of Favos. maximus 

 Quenstedt. 



In connection with this review it may be well to mention a 

 couple of other fossil corals, which are described in Systema 

 Naturte. 



Tubipora fascicularis, first mentioned in S. N., ed. XII, p. 

 1271, without any reference to previous works. Might not N:o 

 XIX have been intended? It is said to be found along the 

 shores of Gotland and also in the limestone. It is of course a 

 Syringopora, which M. Edw. & H. call fascicularis. The identity 

 is uncertain. 



MiUepora solida, S. N., ed. XII, p. 1283 also found »rejecta 

 ad littora Gotlandiae», a Favosites to judge by the description. 

 Wahlenberg (1. c. 109) says that the specimens in the collec- 

 tion of the Society of Upsala which bore the name (since old?) 

 of Milleporites solidus had nearly the same surface as Madr.
