MILLIPEDS FROM DOMINICA — HOFFMAN 37 



Lake on March 26, 1956. A field note with one lot mdicates the 

 specimens were taken from decaying bromeliads. 



The original description of this form was not explicit with respect 

 to the gonopod structure, so that it seems desirable to provide an 

 illustration for future comparison with other Antillean species. 



That E. dominicana is not an introduced synanthropic form seems 

 indicated by the fact that Dr. Clarke's material came from inland 

 high-elevation locaUties, whereas the species was not taken around 

 Roseau by such an experienced collector as H. F. Loomis, 



Order Spirobolida 

 Family Trigoniulidae 



Spirostrophus naresi Pocock

Spirostrophus naresi Loomis and Hoffman, 1948, p. 51 (this paper contains a 

 fairly complete synonymy for the species) . 



Two large collections of this widespread commerce species were made 

 at Antrun at 1,000 ft. on March 10, 1956, and at West Cubrits at 

 500 ft. on March 28, 1956. Notes made at the latter locality state: 

 "Soil, leaf mold, and dry leaves on dry hghtly wooded hillside." 



Ramage did not obtain naresi on Dominica, but Loomis found it to 

 be abundant around Roseau in 1932. He also secured specimens of 

 the related Trigoniulus lumhricinus, another synanthropic species, 

 which, however, is not quite as widespread in the Antilles as naresi, 

 and seems to be more restricted to areas disturbed by the activities 

 of man.

Two females of this genus, tentatively referred to the type spe- 

 cies, were obtained at Antrim on March 11, 1956. The vial carried 

 the label "night beating," which suggests that the specimens may have 

 been swept from low vegetation while they were makmg a nocturnal 

 ascent. Numerous other species of spiroboloids are known to climb at 

 night. 



Our previous knowledge of this animal in the Western Hemisphere 

 is due entirely to the work of H. F. Loomis, who took the first recorded 

 specimens on St. Martins and Guadeloupe in 1932, and who sub- 

 sequently found the species on the southern peninsula of Haiti. It is
