and by extending the body and again bringing up the pleon to its 

 reflexed position to push its way along the tube.* 



The tube (see fig. A) is cylindrical, of the same diameter 

 throughout except at each end where it is somewhat widened ; the 

 two ends are quite similar and appear to be equally and indiffer- 

 ently used by the animal. The tube is quite free and unattached 

 and is no doubt carried about by the animal when it moves. The 

 material of which it is made is fairly tough, the surface is smooth 

 and the whole appears to l)e formed from the secretion produced 

 by the glands in the first and second pereiopoda, no sand grains 

 being used as in Cerajnis sisniithi. 



The tubes that I have seen are all of the same shape, but they 

 very much in size, the largest being about -46 inches long and -03 

 inches in diameter, others being of only half these dimensions. 

 Many of the tubes and especially of the smaller ones were empty 

 and I presume that when the animal has grown too large for its 

 tube it leaves it and secretes another and larger one. 



From the description which has now been given of the male of 

 this species it appears that C . jiindersi is not very different from 

 C. sismithi described by Stebbing from Kerguelen Island ; it diff'ers 

 from that species however in the antennae, to some extent in the 

 second gnathopoda and also in the armature of the uropoda. 



DESCRIPTIONS OF THREE NEW AUSTRALIAN 

 LIZARDS. 



By J. Douglas Ogilby. 



L Gymnodactylus sphyrurus, sp. nov. 



Head rather large ; a strong transverse ridge crosses the occiput 

 immediately behind the eyes, ending on either side in a blunt 

 point placed at the postero-superior angle of the orbit ; from this 

 runs forward an inwardly curved, elevated, supraciliary ridge 

 which is continued on the snout by a conversely curved angular 

 canthus rostralis ; these ridges form the margin on the forehead 

 of an oval, and between the orbits of a subtriangular, depression; 

 loreal region concave ; the length of the snout is one and two-fifths 



* Some very interesting remarks on Cerapus abditus were given many 

 years ago by Templeton, see Stebbing's " Report on the ' Challenger ' 

 Amphipoda," p. 168.
