reddish-brown colour, about an inch long, 

 with a flat, thin body, and yellowish legs. 



Dr. Leach made it the type of his genus 



Liili'ihius, a word meaning that the Centi- 



pede_ lived under or amongst stones. One 



species is very common ia this country, it is 



| named L. forcfpatus. 



There are other species in the collection 

 of the British Museum, from which they 

 were described by G. Newport, F.R.S., &c., 

 a gentleman who has published a most ad- 

 mirable monograph of the Scolopemlriike 

 and their allies, in a recent volume of the 

 Linnzuan Transactions. From the numerous 

 references to the British Museum, the stu- 

 dent will see how rich our great national 

 establishment must be in this important 

 order of the Animal Kingdom. 



CENTRISCUS, or SEA-SNIPE. Ccn- 

 triscus scolopax.) A genus of Acanthopte- 

 rygious fishes, principally distinguished by 



their having a long tubular snout ; the body 

 compressed, and inclining to an oblong oval 

 form ; the abdomen carinated ) and the 

 belly-fins united. [See TRUMPET-FISH.] 



CENTROLOPHUS. A genus of Acanthop- 

 terygious fishes, the technical characters of 

 which are ; body elongate, covered with 

 minute scales ; te th small and numerous ; 

 palatine without teeth ; one long dorsal fin. 



CENTRONOTUS. A genus of Acauthop- 

 terygious fishes, family Scomberidce ; in 

 which the spines are free or unconnected by 

 membrane, and ail have ventral fins. 



CENTROPOMUS. A genus of Acanthop- 

 terygious fishes ; a well known species of 

 which is called the Sea-pike (Centroziomw 

 undecimaJis), and is common throughout 

 South America, where it forms a consider- 

 able article of consumption. The Sea-pike 

 sometimes weighs as much as twenty-five 

 pounds : the form of its body is elongate ; 

 its colour is greenish-brown above, and sil- 

 very beneath. 



CENTROPRISTES. A genus of Acan- 

 thopterygious fishes ; one species of which, 

 (Centropristes nigricans), the Black-perch 

 or Black-bass, is of a deep olive-green colour 

 above, and of a pink hue on the under parts ; 

 but it is mostly remarkable for having the 

 tail doubly notched, the central and two 

 outer parts projecting. 



CENTROPUS. A genus of Scansorial 

 Birds. [See PHEASANT CUCKOO.] 



CEPHALOPODA. A class of Molluscous 



animals, characterized by the possession of 



I locomotive organs (or feet) around the head ; 



they are, however, not feet, but prolonged 

 tentacula, or fleshy processes, which project 

 forwards from the head, and more or less 

 conceal the mouth. In the whole range of 

 molluscous animals, the Cephalopoda are 

 the most highly organized : they present 

 undoubted rudiments of an internal skeleton, 

 and contain digestive, secretory, respiratory, 

 and generative organs. The nervous system 

 of the Cephalopods approaches that of the 

 lower fishes in many particulars ; and they 

 are almost exclusively marine in their habits. 

 The natural division of the class is into those 

 Cephalopods which are naked, and those 

 which are testaceous, (f. e. protected by an 

 external shell.) Of the former, the common 

 Cuttle- fib, and of the latter, the Nautilus, 

 may be taken as examples. 



CEPHUS. A genus of Hymenopterous 

 insects. The Cephus pj/ffinceus, which is 

 common on flowers, particularly buttercups, 

 is about one-third of an inch long ; black, 

 with two yellow fasciae on the abdomen : 

 and its larva is said to live in the stems of 

 wheat. 



CEPOL A. A genus of Acanthopterygious I 

 fishes, the bodies of which are much com- 

 pressed and elongated. [See BAND-FISH.] 



CERAMBYCnXSJ. A family of Coleop- 

 terous insects (Lonyicornes) ; the most dis- 

 tinguishing feature of which is the very 

 great length of their antennae. They are 

 found in all parts of the globe, but they 

 abound most in hot climates. They deposit 

 their eggs in old and decaying trees, which 

 the larvae afterwards feed upon, and thereby ; 

 assist in removing. The body of these insects 

 is long and subdepressed, occasionally sub- 

 convex i the maxillary lobes are distinct : 

 and membranaceous ; the femora often 

 clavate ; and the tarsi short. Mr. Westwood, 

 to whose " Modern Classification of Insects " 

 we are so much indebted, observes that they j 

 are "generally of an elegant form, and 

 beautifully variegated in their colours : they 

 are found in forests, hedges, or woods, : 

 sitting upon the trunks of trees, or more i 

 rarely upon flowers. Some of the exotic \ 

 species are remarkable for having the an- i 

 tennoc and legs covered with thick pencils of 

 hairs ; others are distinguished by the emis- I 

 sion of a fragrant odour, not unlike that of ' 

 attar of roses, which is so powerful, that the : 

 insects may be discovered upon trees by i 

 passers by, in consequence of the scent dif- I 

 fused through the air, and which is retained 

 for a considerable period after death. Hence 

 the generic names Callichroma and Aromia, 

 proposed for these insects by Latreille and 

 Serville. The Cerambyxmoschatus, Linn, (or 

 Musk Beetle, as it is generally but impro- 

 perly termed, the scent scarcely resembling 

 that of this drug) is the only British species 

 belonging to this scented group : it is more 

 than an inch long, of a fine green colour, 

 and is abundant upon willows in the neigh- 

 bourhood of London." It has been con- 

 jectured that the fragrance, which is always 

 much more powerful in the female, may be 

 intended, like the light of the glowworm, as 

 a guide for the males. The author just
