The following should be added to my paper under the 



above title, which appeared in the 'Journal of Conchology' for 



October, 1893 : — 



Terebratula septata Phil. Dr. Jeffreys, in ' B. C. ' vol. ii., 

 p. 14, writing on T. cranuivi, says that the young 'are 

 furnished with a very distinct and prominent crest or ridge, 

 placed inside and nearly in the middle of the lower valve. 

 . . . > This character also occurs in T. septata Phil., 

 and is remarkably developed in that species ; but the 

 foramen is incomplete in T. crajiium and entire in T. 

 septata.'' [These remarks apply not to the young of 

 T. cranium but to that of T. septata^ and both were 

 dredged together in Shetland. It was not figured nor 

 noticed by Jeffreys in his work, but full particulars and 

 figures will be found in the ' Lightning ' Report, and it is 

 well figured in Sowerby's Index]. 



In the 'Porcupine' cruise of 1869 about thirty speci- 

 mens of this fine brachiopod were obtained alive in one 

 haul of the dredge, besides numerous fragments, in 345 

 fathoms in the Shetland Channel. Single specimens and 

 other fragments were also obtained at different depths in 

 the same cruise. 



Led a pern u la Miill. I think this species has sufificient claim 

 to be admitted into the British List. Dr. Jeffreys dredged 

 a small live specimen and a valve off the Shetlands, but 

 hesitated to introduce it as British until he had obtained 

 a full-grown specimen. Although he did not succeed in 

 this, perfect dead shells and some valves have been taken 

 in Loch Duich, Rosshire, and St. Magnus Bay, Shetland
