580 SCIENTIFIC RECORD FOR 1882. 



Limulus differs from Arachnids " in having tracheae, no spiracles, and 

 no Malphiffiau tubes," and "also in having compound eyes, no functional 

 mandibles or maxillee," &c. Professor Packard especially objects to the 

 comparison of the nervous system of Limulus with that of the Scorpion ; 

 in reference to Professor Lankester's claim that " between the sixth ab- 

 dominal segment and the spine there are six segments," he ventures to 

 suggest that four of these segments are purely imaginary ; in opposition 

 to Professor Lankester "would continue to regard the anal spine as the 

 telson"; repudiates Professor Lankester's interpretation of the nature of 

 the compound eyes, the respiratory amellse, the four last pair of biramous 

 respiratory feet, and the " parabranchial stigmata" of Limulus, and cites 

 the alleged discovery of a naupliiform larva of the Japanese Limulus by 

 WillemoesSuhm. 



Professor Mosely, in answer to Professor Packuard, renews expression 

 of faith in the views of Professor Lankester as to the relationship of 

 Limulus to the Arachnids, and shows that Willemoes-Suhm was mis- 

 taken in referring this naupliiform larva to Limulus.
