lignum testa flexuosa ") is applicable to almost any species of 

 Teredo ; and the expression used by Linnaeus, * calamitas navium 

 ex Indiis in Europam propagata," would refer rather to some 

 exotic than to a European species. In the 13th (or Gmelin's) 

 edition, one of the generic characters of Teredo, describing the 

 pallets as " lanceolatis," is peculiarly appropriate to T. Norvagica. 

 The T. marina (or " Hollandische see-wurm ") does not, I believe, 

 occur in sailing ships, but only in piles or fixed wood. I exa- 

 mined in vain the Linnsean Collection (which has been partly 

 arranged by Mr. Hanley) for Teredines, but could not find any ; 

 and Mr. Hanley admits, in his valuable work entitled 'Ipsa 

 Linnsei Conchylia/ that unfortunately no specimen was preserved 

 in it, so as to ascertain which species Linnseus meant by his 

 Teredo navalis*. Under these circumstances, I think I am justi- 

 fied in restoring the prior and appropriate name of " marina" 

 given by Sellius, who used it in a legitimate sense to distinguish 

 this species from those described by Vallisnieri and other 

 authors.

Flora of Cambridgeshire ; or, a Catalogue of Plants found in the 

 County of Cambridge. By C. C. Babington, M.A., F.R.S., 

 F.L.S. Van Voorst, 1860. 



The plants of Cambridgeshire have occupied the attention of many 

 eminent botanists : Mr. Babington mentions, in his ' Introduction,' no 

 less than sixteen treatises bearing upon his subject. But as botany 

 has advanced, so has the surface of the country greatly changed 

 since the times of Ray and of Relhan. With the progress of agri- 

 culture and drainage, many species have become scarce, while some 

 have altogether disappeared ; on the other hand, large additions 

 have been made to the list, through the industry of Mr. Babington 

 and his colleagues. Hence the need of a new Flora ; and we are 

 glad to think the task has fallen into the able hands of the author of 

 the * Manual of British Botany.' 



Mr. Babington has spared no pains to render his work as complete 

 as possible. The older writers have been scrupulously consulted, 

 and the plants referred to their earliest finders. The whole county 



* The following extract from Mr. Hanley's work, which was published 

 in 1 855, will confirm the view I have taken as to the necessity of rectifying 

 the nomenclature of this species : — " Teredo navalis. It is impossible to 

 determine, from the language of Linnaeus, to what particular species of 

 ship-worm the very comprehensive term navalis should be restricted. Our 

 author has not indicated the possession of examples ; consequently his 

 cabinet affords no assistance in the investigation."
