32 Dr. Deakin on new species of Verrucaria and Sagedia. 



I need not say that I was unacquainted with this passage when 

 I received the communication from Mr. Gosse, to whom, I be- 

 lieve, in my reply I mentioned the likelihood of his animal being 

 identical with that discovered by Mr. Cocks and Mr. Alder. 



In the paper referred to are many notices of new marine ani- 

 mals, including several zoophytes, to which the attention of the 

 explorers of our seas might well be directed. 



The fact of the occurrence of the Bryarea Scolopendra in the 

 British seas was first made known by myself, in a communi- 

 cation to the Wernerian Society in 1840; and at the Meeting of 

 the British Association in 1849, when Dr. Ball gave an account 

 of its discovery in Ireland, much information was communicated 

 by several naturalists present respecting this very beautiful and 

 still anomalous animal. 



V. — Description and Illustrations of new species of Verrucaria 

 and SaQcdia. found about Torquay, Devonshire. By Richard 

 Deakin, M.D. 



[With Four Plates.] 



Verrucaeia, Pers. 



Apothecia globose, enclosed within or protruded above the 

 thallus. Nucleus gelatinous, enveloped in a tunic, and entirely 

 or partly covered with a black or brownish peritliedum (not con- 

 tracted into a neck), perforated with a minute or dilated pore, 

 and often papillated at the apex. Sporidia in asci. Thallus 

 horizontal, crustaceous. 



V. neglecta. (Plate I. fig. 1.) 



Thallus crustaceous, a dark dull olive-green, warty and uneven, 

 unequally cracked, upon a black substratum, indeterminate; 

 apothecia numerous, crowded, black, immersed, conico-hemi- 

 spherical, with a naked subpapillated apex and large open pore ; 

 perithecium dimidiate ; nucleus brown, in a black tunic ; sporidia 

 small, oblong, single-celled. 



Thallus in large, spreading, indeterminate patches, of a dark 

 dull olive-green, uneven, warty, and more or less granulated, 

 irregularly cracked, becoming greener and continuous when 

 moistened,, here and there showing the black substratum which 

 forms a thin layer beneath the whole, and often forms a margin 

 beyond the edge of the outer coat» When the plant is grown in 

 shady places and not exposed to the sun, it has a much more 

 powdery appearance, is continuous, not cracked, and in this state 

 closely resembles the V. trachona, Tayl. Apothecia numerous, 

 crowded, black, at first entirely covered by the thallus and hemi- 

 spherical, becoming more conical and naked at the apex, often
