Fam. 5. H T H A M A L I D IE. 

 CHTHAMALUS STELLATUS (Poli). 



Common between tide-marks and in shallow water. Mr. 

 Spence Bate has figured the young reared by him at 

 Plymouth (" On the Development of the Cirripedia," Ann. 

 & Mag. Nat. Hist. ser. 2, vol. viii. p. 324, pi. vii. figs. 11, 

 14; pi. viii. figs. 12, 13); his name for the species being 

 "Chthamalus depressus?, Po\i = Salamispunctatus, Montagu."

 PYRGOMA ANGLICUM, G. B. Sowerby. 



Not uncommon off the coasts of Devon and Cornwall, 

 more especially off" the latter. Attached to the calyx of Caryo- 

 phullia ci/athus off Plymouth aud Polperro (A. M. N.) ; 

 Falmouth ( W. P. Cocks). 



Fam. 7. VERRUCID^E. 



VERRUCA STROMIA (0. F. Miiller). 



This species was described by Miiller in 1776, and in the 

 following year it was described by Pennant under the name 

 Lepas striata. It is dredged attached to shells and stones 

 not unfrequently off the south-west coast. 



Tribe II. GRYPTOSOMATA, A. Hancock. 

 = ACROTHORACICA, Gruvel. 



Fam. TRYPETESID^E. 



TRYPETESA LAMPAS (A. Hancock). 



1849. Alcippe lampas, A. Hancock, Ann. & Mag. Nat. Hist. ser. 2, 



vol. iv. p. 303, pis. viii. & ix. 

 1853. Alcippe lampas, Darwin, Monog. Cirripedia, Balanidae, p. 530, 



pi. xxii. 

 1903. Trypetesa lampas, Norman, Ann. & Mag. Nat. Hist. ser. 7, 



vol. xi. p. 309. 



Hancock instituted a new Order Cryptosomata to receive 

 this genus ; Darwin rejected it, and even embraced this 

 genus in the Fam. Lepadidce. The name Alcippe being 

 previously in use among Birds, it has been necessary to 

 substitute a new generic name.

 Darwin). In Buccinum undatnm off Falmouth ( \\ r . P. Cocks}.
