Carciuology (icapKiVos, a crab, \6yos, discussion), the natural 

 history of Crustaceans, 495. 



Cardiac (Kap$iaic6s, belonging to the heart, KapSia) ; from 

 analogy with vertebrates, the anterior part of the 

 stomach in Amphipoda is called cardiac, without refer- 

 ence to the actual position of the heart, 482. 



Cardio-aortic 1 valves ; arterial ostia ; these connect the heart 

 with the upper and the lower aorta, opening at the 

 systole to admit the passage of the blood, and closing 

 at the diastole to prevent its flowing hack from the 

 aortas, 505, 526. 



Cardio-pericardiac openings ; venous ostia ; the oblique lateral 

 orifices of the heart, which admit the blood into it from 

 the pericardium, when the heart dilates at the diastole ; 

 during the systole they are closed. Normally they occur 

 in pairs in the second, third, and fourth perseon-segments ; 

 in Corophium only in the fourth segment, 505, 527. 



Carpopodite (Kapn6s, wrist, irovs, foot), the fifth (fourth free) 

 joint of the leg, 290. The equivalents in different

Cephalon (K€<pa\ri, head), head, tete, Kopf, Kopfsegment, cabeza, 

 caput, cephalothorax, 259; the front portion of an Amphi- 

 pod, comprising (theoretically) seven coalesced segments, 

 of which the first six are properly cephalic, the seventh 

 being homologous with the first of the three thoracic 

 segments in the Insecta, 264, 289, 463. 



Cephalostegite («ecf>aA^, head, attyw, I cover), 463. 



Cerebral ganglion. See Brain. 



Chelate (xv^t a claw), cheliferous, 27, 44 ; cheliform, 29, 54, 

 88, 179, 588 ; with a didactyle hand, 97, 143, 1622 ; 

 Scheere, 597 ; properly used of a limb in which a 

 movable joint closes almost throughout its whole length 

 against the lateral margin of another joint, but in early 

 writers often equivalent to subchelate. 



Chiasma, a crosswise position, like the strokes of the Greek 

 letter x , 1646, 1652. 



1 On p. 526, line 30, reference is made to an expression used by Delage, ' 

 aortique" would seem to be the one intended.

Chitin, Chitine (xirdv, a coat). Huxley, The Crayfish, 

 p. 347, in regard to the exoskeleton of the crayfish, 

 says: — "The animal matter consists for the most part 

 of a peculiar substance termed Chitin, which enters into 

 the composition of the hard parts not only of the Arthrn- 

 poda in general, but of many other invertebrated animals. 

 Chitin is not dissolved even by hot caustic alkalies, 

 whence the use of solutions of caustic potash and soda in 

 cleansing the skeletons of crayfishes. It is soluble in 

 cold concentrated hydrochloric acid without change, and 

 may be precipitated from its solution by the addition of 

 water. Chitin contains nitrogen, and according to the 

 latest investigations (Ledderhose, ' Ueber Chitin und 

 seine Spaltungs-produkte:' Zeitschrift fiir Physiologische 

 Chemie, II. 1879), its composition is represented by the 

 formula C, 5 H., l 3N 2 O 10 . " (See also Milne-Edwards, Hist, 

 nat. des Crust., t. i. p. 10, and Darwin, The Lepadidie, 

 p. 30). 134, 279.

 distinct segment of the body''), 215, 256, 259, 2S9, 601. 

 Chromatophore (xp&fia, colour, cptpa, I bear), 477, 548. 

 Cilia, cilia? (cilium, in Latin an eyelash), variously applied to 

 delicate hairs and slender hair-like appendages. The 

 term seems inappropriate for the "auditory cilia" of Bate 

 and Westwood, see pp. 290, 504, which, as those authors 

 themselves remark, are quite distinct from the "auditory 

 cilia " of Hensen.

 Colouring. Mr. Murray informs me that nearly all the Amphi- 

 poda taken in the dredge and trawl from deep water were 

 of a red or rose colour, the eyes being frequently golden 

 coloured. 221, 319, 382, 416, 430, 437, 438, 468, 578,
