68 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 89 



Last segment broadly rounded behind, the median third of the 

 margin simple, each lateral third occupied by two lobes. 



Gonopods with each enlarged basal joint continued at the apex 

 of the inner side into a long, erect lobe nearly equaling the tip of the 

 inner joint and guarding it on the outer side. Inner joint coarsely 

 serrate along its outer margin, the tip acute (fig. 33, b). 



Legs similar in both sexes. Males with the coxae of the sixth legs 

 moderately separated ; those of the seventh legs twice as widely sep- 

 arated, the sternum flat ; legs following the gonopods moderately 

 separated, the sternum bearing two round tubercles. 



Type.— \J. S.N. M. no. 1109. 



Although the following species of millipeds were not collected by 

 the expedition of 1932 it seems advisable to call attention to them 

 here, inasmuch as they were not mentioned by Chamberlin in his list 

 of the diplopods of the West Indies.'^ 



SPIROBOLUS BAHAMENSIS Bollman 



Spirobalus bahamensis Bollman, U.S. Nat. Mus. Bull. 46, p. 192, 1893. 



Known only from the original collection from the island of San 

 Salvador. This species may belong to the genus Arctobohis, as the 

 number of clypeal foveolae apparently exclude it from the genus 

 Rhinocricus. Arcfobolus is common throughout the eastern United 

 States, but no species are known from any of the Bahama or West 

 Indian Islands. 



RHINOCRICUS MODESTIOR Silvestri 



Rhinocricus modestior Silvestri, Bull. Amer. Mus. Nat. Hist., vol. 24, p. 570, 

 1908. 



Known only from Puerto Rico. 



RHINOCRICUS SERPENTINUS Pocock 



Rhinocricus scrpciitiiuts Pocock, Journ. Linn. Soc. London, vol. 24, pp. 501, 502, 

 1894. 



Known only from St. Lucia. 



INODESMUS JAMAICENSIS Cook 



Inodesnius jainaiccnsis Cook, Brandtia, p. 25, 1896. 



Known only from the original collection from Jamaica.
