580 SCIENTIFIC EECORD FOR 1882. 



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

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

 mandibles or maxillse," &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 

 Willemoes-Suhm. 



Professor Mosely, in answer to Professor Packnard, 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.
