166 ON THE ANATOMY OF ENTOMOSTRACA. 



dified, but all these legs have the innermost lobe armed with a 

 row of strong setee arranged transversely, and evidently in- 

 tended to convey the food to the mouth by generating a current 

 in that direction. In this transverse arrangement of the setge of 

 this lobe we again trace a resemblance to Livmadia. 



The hairless lobe in this species is very small as compared 

 with that noticed in Dapluiia carinata. It does not appear at all 

 in Mr. Baird's Plate of E. lamellatus. I have already pointed 

 out the remarkable difference in the last pair of legs from that 

 figured in Mr. B.'s work. 



The first pair appear to have been modified with a view to 

 assist the animal in swimming, and help to account for its satis- 

 factory progress in the water. The long finger on the 5th pair 

 seems to be intended to assist in walking among the decaying 

 vegetable matter in and among which the little creature obtains 

 its food. 



On the whole, the examination of the branchial legs of this 

 species suggests the idea of a return towards the Phyllopoda. 

 Most of the species of the Lynceidce are so exceedingly minute 

 that it is difficult to perform the operation of amputation ; and 

 without it the examination of these parts is quite impossible. 



Let me suggest, in conclusion, that if any other observer 

 should meet with a tolerably large species of the Lynceidce he 

 should make it the subject of a careful examination. 



And one other suggestion I would make for the benefit of 

 those members of our Society who live in Sydney or near the 

 coast. And it is this — that the Marine Entomostraca are very 

 numerous, exceedingly interesting, easily procurable, and, as far 

 as our own species are concerned, quite unknown. I have 

 drawings of a Cijpridina and a few parasitic species (including at 

 least one new genus) which are quite at the service of any who 

 will take up the study.
