34 SUPPLEMENT TO THE 



Valenciennes" — is too short, and would be applicable to several species of Spirifera. The 

 original specimen so named is in the Museum of the Jardin des Plantes, and is known 

 to French palaeontologists. 



Dr. Gosselet is quite right when he objects to the law of priority being enforced 

 when a species has been too briefly described and is unaccompanied by a figure ; but, if this 

 reasoning is to hold good in the present case, how many specific names would have to be 

 expunged that are now generally adopted under similar circumstances ! Until some 

 international law has been established in which no new species that is unaccompanied by 

 a figure can hold claim to priority we cannot, I should think, deprive Valenciennes of 

 the same privilege which has been allowed to so many others. 



Good specimens of Sp. lavicosta have been found by Mr. Champernowne at the 

 Railway Cutting at A.shridge, near Totnes. Distorted examples have also been collected 

 by the same geologist in slate at Hanger's Quarry, near Sandwell, in Devonshire, as 

 well as in slate at Englebourne Slate Quarry, near Harbertonford. Along with it were 

 found distorted specimens of Sp. primava and Sp. speciosa. 



In pi. 52, figs. 1 and 2, of the Atlas of his work, ' Die Brachiopoden,' 1871, 

 Quenstedt gives two excellent figures of the spiral appendages of the species under 

 description, one of which we have reproduced so as to complete its history. 



Mr. Whidbome has met with distorted fragmentary examples of Sp. lavicosta in the 

 Middle-Devonian limestone at Hope's Nose, near Torquay. 



21. Spirifera cultrijugata? Roemer. Dav., Dev. Mon., PI. VHI, figs. 1, 2, 3. 



It was with much uncertainty that I referred some specimens found at Looe to Roemer's 

 species. Perhaps Sp. primceva, Steintinger, ' Geol. Beschreibung der Eifel,' p. 72, 

 pi. vi, fig. 1, is the species to which our English specimens should be referred. The 

 material at my command was so incomplete that it prevented my arriving at any 

 positive conclusion. 



22. Spirifera Urii, Fleming. Dav,, Dev. Mon., PI. IV, figs. 25—28. 



Since describing this species at p. 41 of my 'Devonian Monograph' I learn that 

 several well-preserved specimens of the shell have been found by Mr. Whidborne in 

 the Middle Devonian at Lummaton, near Torquay.
