90 BULLINA. 



genus Bullinula of Dr. Beck, consists of those species wliicli have 

 more produced spines, fig. 253. The Bullae are marine, and 

 inhabit all climates. The fossil species occur in tertiary beds. 

 Since the first edition of this work was published, a very valuable 

 monograph of the family by Mr. Adams has appeared in Sowerby's 

 Thesaurus, part 11, in which the animals and their shells are 

 arranged in the following genera or subgenera, Bullina, Aplus- 

 trum, Hydatina, Cornatina, Utriculus, Akera, Scaphander, Bulla, 

 Haminea, Atys, Cylichna, Volvula, Linteria, Cryptopthalmus, 

 Phaneropthalinus, Sormetus, Philine, Doridium, Chelidoniira, 

 Gasteropteron, and Atlas. Fig. 247 to 253. 



BULL^A. Lam. BULLA aperta, Auct. fig. 248. 



BULLtEAJSTA. (" BuUeens, Lam.") A family belonging to the first 

 section of Lamarck's order, Grasteropoda, containing the genus 

 Bulla. The genera Bullsea, Akera, Aplustra, Atys, Scaphander, 

 Bullinula, into which it has been divided, may all be fairly included 

 under the name Bulla. 



BTJLLIA. Gray. 1834. A genus of shells partly resembling 

 Buccinum, and Terebra in general form, being more elongated 

 than the former and more ventricose than the latter. Mr. Gray 

 remarks in the Synopsis of the British Museum, page 114, that 

 the Bulliae resemble the ISTassse in most characters, " but they 

 have a very large, broad foot, and the hiader part of the inner 

 lip of the shell being extended beyond the mouth, forms a raised 

 enamelled band round the suture of the whorls, as is also the 

 case with the Ancillarise and some Volutes." Bullia vittata, fig. 

 427, is an example of the genus. The name Subula is given by 

 De Blainville to the other species of Terebra, so that if both 

 these genera were admitted, the old genus Terebra must be 

 expunged. PI. xx. fig. 427.
