Testa inequivalvis, adherens, crassa, subponderosa, valvis viz auriculatis, radiatim liratis. valvis ambabus lata, edentula, foved subprofundé ob- longa in medio. lateralis. Shell inequivalve, adhering, thick, rather ponderous, valves slightly auriculated, radiately ridged. Hinge area in both valves broad, toothless, with a rather deep ob- long pit in the middle. Muscular impression very large, sublateral. This genus was founded by M. Defrance with two fossil species, and had been received by conchologists, when Mr. Gray discovered that a large bivalve shell in the British Museum, referred by him with a note of doubt to Lima, belonged to it. It was in August, 1826, that Mr. Gray announced this discovery in the ‘Annals of Philosophy.’ The shell which he had described in the same periodical as Lima? gigantea, he now referred to the fossil genus of Defrance, altering the generic name, for reasons which we think untenable, to Hinnita, and afterwards to Hinnus. Another shell of similar generic character turned up in the old collection of Dr. Goodall, and this Mr. Sowerby de- scribed as Hinnites corallinus in the third volume of the ‘Zoological Journal.’ M. Deshayes and Mr. Sowerby, by reason of the peculiarity of its mode of attachment, re- ferred the Ostrea (Pecten) sinuosus, which is probably iden- tical with the Linnean Ostrea (Pecten) pusio, to Defrance’s genus, but the relationship has not been confirmed by subsequent researches. Messrs. Forbes and Hanley have shown, in their ‘ History of British Mollusca,’ that this Pecten lives free when young, and merely attaches itself in the adult state. The shell then takes an irregular form of growth, still preserving its generic characters. The Pecten pusio is represented in the accompanying plate in the state in which it has been called Ostrea and Hinnites sinuosus, but inasmuch as it does not possess the broad, solid, car- dinal area and heavy Spondylus-like character of Hinnites, it should not be included in the genus. Area cardinalis in Impressio muscularis perampla, sub- Hinnites has more of the general character of Spondylus than of Pecten, but the hinge is distinct, being without teeth, and produced into an area equally in both valves. One of the species inhabits the Old World, and the other the New. Species 1. (Fig 2. Mus. Brit.) HINNITES CORALLINUS.

The outer surface of this specimen is very much broken and worm-eaten, but very characteristic, both in respect of sculpture and colour. The interior is remarkable for its conspicuous muscular impression, the surface being sculptured with a strong veinous net-work. Species 2. (Fig. 3. Mus. Brit.) HINNITES GIGANTEUS. Hinn. testa ovatd, converd, radia- tim scabroso-lirata, liris prope umbones levibus, nitide binis ; aurantio-rufescente, vel albidd, intus alba, prope cardinem vivide purpureo-violaced. THE GIGANTIC HinnrvEs. Shell ovate, convex, radiately scabrous-ridged, smooth and neatly disposed in pairs near the umboes; orange-red, or whitish, interior white, stained with rich purple-violet near the hinge. Gray, Annals of Philosophy, 2nd Series, vol. xii. p. 103. Hab. California and Straits of Juan Fernandez. The ridges of this species, which is of more convex oblong growth than the preceding, are here and there at nearly equal distances larger. One of the principal cha- racteristics of the species is the deep purple-violet colour- ing of the hinge.

Testa ovato-trigona vel transversa, lateribus paulisper hians ; umbonibus prominentibus. Dens cardinalis in utraque valvd compressus, plicato-canaliculatus, cum adjecta fo- veold intus prominuld. Dentes laterales duo compressi, utringue prope cardinem inserti ; ligamentum internum, in foveolé cardinali insertum. Shell ovately triangular or transverse, a little gaping at the sides; umboes prominent. Cardinal teeth in each valve compressed, plicately channelled, with the interlying pit rather prominent within; two lateral compressed teeth inserted on each side near the hinge; ligament internal, inserted in the hinge pit. There is no genus of bivalves which it is more easy to determine than Mactra. The shell has, with little varia- tion, a characteristic triangular form, more or less trans- versely ovate or oblong; and the hinge is distinguished by a prominent central triangular tooth in one valve, which closely interlocks in a corresponding pit in the opposite valve. The Mactre are mostly void of colour, but some are very prettily tinged and rayed with rose or pur- ple. In sculpture they are also deficient, compared with the Tellinide or Veneride, having seldom more than concentric grooves and stria or plait-like ridges. The anterior or front half of the shell is, with few exceptions, the shorter, and this is sometimes concentrically grooved and striated while the posterior side is smooth. Beneath the umboes on the anterior side a neat heart-shaped lunule is generally formed, and the striz of the valves mostly converge on the shield of this in a more regular and ele- gantly developed state. On the posterior side the liga- mentary area is more broadly spread, and mostly angled on each side. Some of the Mactre, more especially those inhabiting the Northern Seas, are ponderous and Mya- like; the majority of the species inhabiting the tropical seas are thin, some almost transparent, and most elegantly wave-wrinkled and striated. The localities noted in the following monograph will show that the genus is pretty evenly distributed over the globe, from the Arctic Seas along both sides of the African continent to Van Diemen’s Land in the eastern hemisphere, and from the North Ame- rican Seas to Panama and Columbia in the western. Lamarck enumerated about thirty species in his Anim. sans vert., but several have been described subsequently by different authors, and the genus has lately undergone a complete revision by M. Deshayes, who has been staying in this country for the purpose, while assisting in the ar- rangement of Mr. Cuming’s and our national collections. The species are brought up in the present monograph to a hundred and twenty-five in number. It will be seen that several well-marked groups are included in this number, all belonging to the Lamarckian genus Mactra, but deno- minated as genera by the more advanced conchologists, under the names of Mulinia, Schizodesma, Cypricia, Raeta, Standella, Spisula, etc., as will be seen by the synonyms.

Dr. Gould, of Boston, United States, describes this large species as living abundant about the sandy beaches of Massachusetts. At low water it is dug out of the sand with shovels; at higher tides, when the shell is open, the fishermen wade into the water, thrusting a pointed stick into the sand before them as they walk along. Whene th stick passes between the valves, the animal closes the shell upon it and is drawn up. March, 1854. Mactra, PU HL Sowerby, del et. bth. F. Reeve , MAC T RA: Puate IT. Species 9. (Mus.

Lutrarta, Fé T. LUTRARIA. Puate I. Genus LUTRARIA, Lamarck. Testa equivalvis, inequilateralis, oblongo-ovata, plerumque compressiuscula, lateribus hians, sordidé albé, epi- dermide fuscd vel olivaceo-fuscd plus minus induta. Cardo centralis, latus, dentibus duobus plano-cochle- ariformibus lamind trigond erecta, dentibus laterali- bus nullis. Impressio muscularis pallit sinu magno. Shell equivalve, inequilateral, oblong-ovate, generally rather compressed, gaping at the sides, dirty-white, covered more or less with a brown or olive-brown epidermis. Hinge central, broad, with two flat spoon-like teeth, and an erect triangular lamina, no lateral teeth. Muscular impression of the mantle with a large sinus. Of the miscellaneous assemblage of species described by Lamarck under this head, only two remain as true repre- sentatives of the genus, Lutraria oblonga and L. eiliptica, both inhabitants of the British Seas. More than a dozen species from foreign sources have since been added of the same exact type, and we have the pleasure of illustrating them as a very natural and well-defined group. The most abnormal forms are those which have been separated by Mr. Gray under the generic title of Zenxatia, comprising L. acinaces, Deshayesii, and Cumingiana; and L. lanceolata, which is the genus Resania of Mr. Gray. In the last the interior of each valve is characterized by two very promi- nent ledges converging from the hinge, on one of which rests the broad spoon-shaped tooth, as represented in Plate V. They are all of a smooth dull colourless hue, more or less covered with a dirty-brown or olive epider- mis, and present no sculpture beyond strie or wrinkles following the lines of growth. The species are limited in number and widely distributed, being from Australia, New Zealand, Moluccas, Philippines, China, and the Cape or Good Hope. They are all natives of the Old World. Species 1.

But let that infant’s hand draw near, It shrinks with quick instinctive fear, And clings as close, as though the stoue It rests upon, and it, were one; And should the strongest arm endeavour The Limpet from its rock to sever, °Tis seen its loved support to clasp, With such tenacity of grasp, We wonder that such strength should dwell In such a small and simple shell.” — Wordsworth. Patella , PUI PATELLA. Puate I. Genus PATELLA, Linnaeus. Testa ovata, plus minus convexa, patellaformi, non spiralis, apice interdum centrali, plerumque plus minus antice inclinato, sepissime radiatim costata vel lirata, inter- dum squamata, margine plerumque crenulata ; tn- pressio muscularis elliptica, anticé interrupta. Shell ovate or rounded, more or less convex, dish-shaped, not spiral, apex sometimes central, generally more or less inclined anteriorly, mostly radiately ribbed or ridged, sometimes scaly, generally crenulated at the margin; muscular impression elliptical, interrupted anteriorly. The Limpets, properly so called, have been collected together under the generic title of Patella, from the re- semblance of their shell to the form of a dish of that name, formerly used by the Latins for carrying meat in their sa- crifices. In structure it is the most simple of all shells, being an unconvoluted shield, covering the soft parts of the animal, more or less raised in convexity, not spiral, inclining to an apex, rarely more than superficially de- veloped, but sometimes bent over anteriorly into a minute hook. From this apex radiate strie, ridges, or ribs, which are sometimes scaled, and have the interstices sometimes wrought into lattice work by concentric ridges. It is only very rarely, however, that the shell is so sculptured, the ribs or ridges being for the most part smooth, though presenting abundant characteristic varieties of form and distribution. The painting of the Patel/e is also exceed- ingly varied; the prevailing pattern consisting of rays, modified by various causes to a degree which renders the different states of a species often extremely difficult of identification. The Patelle inhabit all latitudes, ranging from the Equator to the Arctic Seas, where the P. testudinalis has been found by Sir Edward Belcher in Wellington Channel, the most northern limit of animal life; and they are every- where abundant in their kind. Some of the finest species are found about the Cape of Good Hope. Species 1. (Mus. Cuming.) PateLLtaA Mexicana.

Tae Mexican Limper. Shell oblong-ovate, attenuated in front, rather sharply convex in the middle, flat- tened towards the margin, radiately ribbed, ribs rather compressed, rude, irregular, more or less obsolete, with intermediate scabrous ridges in the young shell ; yellowish-white, here and there very faintly rust- tinged, and very faintly rust-tinged within. Broperip and Sowersy, Zool. Journ. vol. iv. p. 369. Hab. Acapulco; Cuming. Mazatlan; Carpenter. This fine species, the largest, in an eminent degree, of the genus, is of a sharply convex form, flattened towards the margin, distinguished exteriorly by a series of irregular radiating ribs, which soon become obsolete as the shell advances in growth. It is, within and without, of a uni- form white, tinged with rust. May, 1855. . i 1 : pI 4 w A 1 1 4 a} 7 e ie * a A i : : Patella, Pl. Il. PATELLA. Puate II. Species 2. (Fig. a, 6, Mus. Cuming.)
