2ilicis crassis, elevatis, ad marginem ventraleni evanidis; latere 



antico rotundato, i)Ostico subrostrato, margine oblique truncato. 



Hub. Moreton Bay, East Australia, deep water {Mr. Strange). 



This large species is near C. pidchra. Reeve, but differs in being 



more gibbose, less beaked posteriorly, in the plicae being stronger, 



and in wanting the coloured rays. 



5. AsPERGiLLUM Strangei, A. Adams (PI. XV. fig. 5). A. 

 testa cequivalvi, subcequilaterali, alba, transversim sulcosa, 

 umbonibus promimdis. Tubo in/erne clnvso, disco terminali 

 hasi adhcerente, adlatera expansiusculo, margine tubulis minimis 

 ornato, postice subcarinato, jtroducto, tubulis curtis instructo ; 

 superne elongato, tortuoso, carinis obtusis quatuor longitudina- 

 libus, ornato, margine simplice recto. 



Hab. Seas of Australia {Mr. Strange). 



Two specimens of this curious form were collected, one attached to 

 a stone, and the other to the valve of a Mytilus. They were found 

 at Sydney, in shoal water. The fact of the tube being nothing more 

 than the valves greatly expanded and modified, is well shown in one 

 of the specimens. 



6. Trigonia Strangei, A. Adams (PI. XVI. fig. 3). T. testa 

 cequivalvi, incequilaterali, subtrigona, fusca, longitudinaliter 

 valde costata ; costis antiee confertis, postice 'magis distantibus, 

 squamis nodiformibus, transversis, imbricatis, confertis, ornatis; 

 interstitiis transverse crebre striatis ; latere atitico rotundato, 

 postico oblique subtruncato. 



Hab. Sydney, deep water {3Ir. Strange). 



This species' is larger than T. margaritacea, and somewhat re- 

 sembles in the style of sculpture T. uniophora. Gray. The form of 

 the scales on the ribs at once distinguishes it, however ; the shape 

 of the shell, especially the outline of the hind slope, is also very dif- 

 ferent. 



7. Chiton insculptxjs, A. Adams (PI. XVI. fig. 4). C. testa 

 oblonga, valde elevata, valvis terminalibus cceterarumque areis 

 lateralibus radiatim costatis, costis granatis, granis trans- 

 versis, subconfertis, ad marginem obsoletis ; umbonibus cari- 

 natis ; valva terminali antiee umhonata ; areis centralibus 

 longitudinaliter valde liratis ; liris obsolete rugoso-granulatis. 

 Coccinevs areis centralibus lineis nigro-fuscis duabus ornatis ; 

 ligamento luteo-fusco fuscoque articulato squammulato, squam- 

 mulis Icevis, nitidis, convexis. 



Hab. New Zealand, on dead shells, deep water {Mr. Strange). 

 A beautifully sculptured species of a red colour, with two dark 

 parallel lines down the centre of the valves. 



8. Chiton muricatus, A. Adams (PI. XVI. fig. 6). C. testa 

 oblonga, in medio valde elevata, nigro-fusco alboque varie- 

 gata, valvis terminalibus cceterarumque areis lateralibus radia- 

 tim costatis ; costis granis elevatis acutis ornatis ; valva ter-
