334 M. O. A. L. MORCh's REVIEW OF THE VERMETID-E. [NoV. 12, 



Operculum juvenile plamim tenue, inferne vivide coccineum. 



Diam. 1^ m. 



Variat laminis confertissimis et cqnvexitate. 



Hub. In Mavi Mediterraneo. 



In Mr. Cuming's collection is a large flat crust, nearly the size 

 of the hand, showing on the under side white, smooth, cylindrical 

 whorls, with annular contractions, which seems to have been im- 

 bedded in chalk, but does not appear corroding. The representation 

 of Philippi is very like it ; the last whorl on the upper side differs 

 entirely in shape, sculpture, and colour. A specimen from Bivona 

 himself, in Dr. Hornbeck's collection, is very like Mr. Cuming's 

 group. According to Philippi, it is chiefly common near Palermo. 

 According to the locality, Golfo di Tarento, it is probable that the 

 Spiroglyphus represented on Patella tareniina, in Delessert's ' Re- 

 cueil,' pi. 23. f. 7, is the young of this species. 



A small group of agglutinated straight tubes from the Adriatic 

 Sea, by Trieste, in the collection of Mr. Alfr. Benson, furnishes the 

 following form, probably referable to this species : — 



Var. jS. TUBULOSA. 



Serpula annulata. Lam. Hist. 1818, v. p. 364. no. 10; ed. 2. v. 



p. 620. 



S. annulata, Blainv. Diet, des Sc. xlviii. p. 556. 



Fermetus annulatus, Rouss., Chenu, 111. t. 2. f. 1, 1 a. 



" Testis teretibus, gracilibus, annulatim plicatis porrecto-flexuosis, 

 glomeratis." 



" EUe est blanche, et sa masse ressemble a un paquet de petits in- 

 testins allonges " (Lam.), 



This group has the tubes of only If m. diameter; in another 

 group from M. A. W. Malm, at Gotheborg, without locality, the 

 tubes are somewhat larger. The inside of the first whorls, which are 

 all broken, is pale brown. 



To this genus the following species might perhaps be referred : — 



Vermetusinfundibalum, Chenu, 111. t. 10. f. 12 (withayoung one). 



V. costalis. Lam., Cheuu, 111. t. 10. f. 11.
