MR. BRODERIP ON CLAVAGELLA. 265 
CLAVAGELLA ELONGATA. 
Tab. XXXV. Figg. 1—4. 
Clav. camerd elongato-ovatd; valvié liberd elongatd, subtrigond, convead, externe concentricé 
valde rugosd, intus nitente; umbone acuto. 
Hab. in Oceano Pacifico ?

The Astreopora in which this Clavagella is chambered approaches very closely to one 
brought by Mr. 8. Stutchbury from Bow Island, or Hao, in the Pacific Ocean, and I 
have therefore suggested that Ocean as its probable locality. The wall of the coral 
chamber against which the free valve rested, gives as exact an impression of the ex- 
ternal rugosities of that valve as if it had been applied to a surface of wax. 
CLAVAGELLA LATA. 
Tab. XXX. Figg. 8—10 (Testa) ; 11—16 (Animal). 
Clav. camera rotundato-ovaté ; valvé liberd latiusculd, subtrigond, subconvexd, externé con- 
centrice rugosd, intis nitente ; umbone subrotundato. 
Hab. in Oceano Pacifico.

Both valves are nacreous internally, and the muscular impressions!, especially in the 
fixed valve, are very strong.

Clav. testd subrotundatd, rugosd, intis subnitente ; tubo longitudinaliter corrugato.

Mr. G. B. Sowerby, finding that I was writing upon this subject, forwarded to me, 
with his usual liberality, two specimens of Clavagella from Malta. They are in an 
argillo-calcareous tufa? One of them belongs to Mr. Cuming, the other to T. Miller, 
Esq., Surgeon R.N., who brought them to this country. 
The loose valve of Mr. Cuming’s specimen? is not so much rounded as that of 
Mr. Miller’s’, nor are its corrugations so large and distant. Mr. Cuming’s specimen has 
a considerable portion of the longitudinally corrugated tube‘ still projecting from the 
rock ; but Mr. Miller’s appears to have been abraded till it became even with the sur-
