THE MYRIAPODA OF NORTH AMERICA. 89 



Dorsal plates with six sulci, the median straight or slightly curved 

 inwards, the others outwards. Posterior pleura' scabious ; pores numer- 

 ous, small; terminal spine large and robust. Last ventral plate mod- 

 erately wide, sides converging, posterior border sinuate. Length 28 mm , 

 width 3""". 



In the collection are two specimens which I refer to this species. 

 Both have lost most of their legs, especially the anal, of which only one 

 remains and even it is in a mutilated condition so that the tarsal joints 

 can not be counted. 



11. Scutigera sp. ? 



I have received from Poey and Gundlach several specimens of a 

 Scutigera, which I' have been unable to identify satisfactorily with any 

 of the known species.
