2. A new species of Gregarine from North American Diplopods.

eingeg. 22. März 1912. 

 This species of gregarine was first taken from specimens of the 

 Diplopod Paraiulus venustus Wood, collected at the base of Green 

 Mountain near Boulder, Colorado, at an altitude of about 6000 feet, on 

 October 30, 1911. Six of the twenty specimens were infested, each with 

 twenty-five or more gregarines. Two specimens of this same Diplopod 

 out of five taken in Boulder on November 12, 1911, by Miss Rosamond 

 Patton also contained this gregarine. On December 5, 1911 it was 

 again found in two out of seven specimens of Orthomorpha gracilis 

 (Koch) collected by Prof. T. D. A. Cockerell in a local greenhouse. 

 These Diplopods were hosts for but twelve gregarines, eight in one and 

 four in the other. As this Diplopod is an introduced species, occurring 

 in Boulder only in greenhouses, and as Orthomorpha is a genus of another 

 family, the Poly desmidae, the presence of the same gregarine in both 

 Paraiulus and Orthomorpha is the more interesting. Of the other gre- 

 garines of the United States known from Diplopods only one, Steno- 

 phora larvata (Leidy), is recorded from Diplopods belonging to genera 

 of different families. Two other collections of Orthomorpha gracilis were 

 examined from the greenhouse but no gregarines were found. These 

 Diplopods were taken February 8 and February 23, 1912. Since the 

 Paraiulids collected on Green Mountain were reasonably well removed 

 from any chance infection from spores dropped by the Polydesmids and 

 as the native Paraiulids in Boulder were found infested with this gre- 

 garine it seems safe to consider it a native species. It is worthy of note 

 however that the spores of this gregarine are capable of developing into 

 normal gregarines in either of the two Diplopods.
