460 BULLID.E. 



Plancus says that tlie fisliermen in his time called 

 this shell ^' amygdala marina '^ (sea-almond) ; it is the 

 Philine quadripartita of Ascanius, Loharia quadriloba 

 of Miiller,, Bulla bulla of Da Costa, and Bullcea j)lan- 

 ciana of Lamarck ; the fry is Bidla emarginata of Adams. 

 In Gmelin^s edition of the ^ Systema Natur?e ' it is placed 

 among the Testacea as Bulla aperta, and among the 

 Mollnsca as Loharia quadriloba. Among the synonyms 

 quoted by Martini in his ^ Conchylien-Cabinet/ is the 

 fanciful one of ^^ unguis humaria/' derived from Colonna ; 

 the genders are thus treated somewhat in the German 

 fashion. PfeifFer named the South African specimens 

 Bullaa Capensis, and Philippi B. Schi^oeteri. These, 

 like the European, vary in convexity, size of the con- 

 voluted portion, and height of the outer lip. I have 

 in vain attempted to discover a single character by 

 which they can be distinguished. 



And now, good Reader, I should be sorry, if you have 

 complained of my being too voluminous. I never pro- 

 fessed to make this a manual; nor have I yet quite 

 done. Let me remind you of the advice given by 

 Seneca (De Ira, Lib. iii. c. 31. § 3), ^^Age potius 

 gratias pro his qute accepisti : reliqua expecta, et non- 

 dum plenum te esse gaude. Inter voluptates est, su- 

 peresse quod speres.^^ 



The next volume will complete the work, and contain 

 an account of the few^ remaining Pleurobranchiata, the 

 Nudibranchs (by Mr. Alder), the marine Pulmono- 

 branchs, the Pteropods, and the Cephalopods, a Sup- 

 plement to the volumes already published, and other 

 useful matter_, besides plates (plain and coloured) by Mr.
