The former is a common myriapod or milleped ; the latter a 

 large coleopterous insect or beetle found abundantly in decay- 

 ing wood, and whose fat white grub is often met with. In the 

 milleped no less than seven species of lowly entozoans, and 

 in the beetle two, were found, described, and figured. In the 

 cockroach six species had been found, of which two were for 

 the first time made known. Several other new species of 

 entozoans from other insects were also described. 



COELENTERATES 



THE only memoir on any Coelenterata published by the 

 Institution outside of the " Proceedings of the National Mu- 

 seum " was one on the " Lucernariae and their allies," by 

 Henry James Clark, and was in the twenty-third volume of 

 the "Smithsonian Contributions to Knowledge.") 



CRUSTACEANS 



THE Crustacea have received especial attention from the 

 Smithsonian Institution, and are well represented in the 

 United States National Museum ; much has also been pub- 

 lished by the officers in charge of the collection in the " Pro- 

 ceedings of the United States National Museum." But with 

 the exception of the two unimportant articles giving instruc- 

 tions for cooperation and asking for information respecting 

 crawfish, no independent publication on the class has been 

 issued by the Institution. 



INSECTS 



THE insects have been treated of in a number of volumes, 

 in which various orders or other groups were systematically 

 dealt with.
