261. S. recedeiis A. S. A. S. Atl. tab. XIX, fig. 3. 

 KKm, KKt KGn, KMn, s. 1. (7 samples). 



Area: Brazil. 



262. S. reiiiformis Grun. Perag. Diat. de Fr. tab. LXV, fig. 5. 

 KKt, s. I. (3 samples)- 



Area: Honduras, Languedoc, Banyuls, Madagascar, San Thome, Malay 

 Archipelago, Samoa. 



This form, taken by Peragallo (I.e. p. 255) as a separate species, 

 is identical with Grunow's Plagiodiscus nervatus. It is very near to 

 Sur. Gemma and like V. Heurck (Ti-aité p. 374) 1 am most inclined to 

 regard it as an abnormous form of S. Gemma only differing in its outer 

 appearance. 



In a sample from TK I found a Surirella, identical with a „fragliche 

 Form" from the Gazelle-Expedition enfr. A. S. Atl. tab. LVI, fig. 6 and Jan 

 Gaz. Exp. tab. XXI, fig. 23. 



Campylodiscus Ehb.
