THE MYRIOPOD FAUNA OF THE BERMUDA ISLANDS, 

 WITH NOTES ON VARIATION IN SCUTIGERA. 



Ralph V. Chamberlin. 



The present paper is based upon a study of several lots of 

 chilopods and diplopods from the Bermudas, belonging chiefly 

 to the Museum of Comparative Zoology, at Cambridge, Mass., 

 and to the United States National Museum, at Washington, 

 D. C. The collections embrace material secured by Prof. J. H. 

 Comstock, in 1903, the Yale Expedition to the Bermudas in 

 1898, Prof. A. E. Verrill in 1901, Mr. Owen Bryant and Dr. 

 Thomas Barbour in 1903, Dr. R. W. Glaser, Dr. G. B. Goode, 

 and material from the Bermuda Biological Station for Research 

 collected by Prof. E. L. Mark in 1903, and Dr. W. L. Crozier 

 in 1917 and 1918. An examination of this material has brought 

 to light all species previously recorded and six species not 

 previously known to occur upon the islands, bringing the total 

 of chilopods and diplopods together to fifteen species. These 

 forms are as follows : 



DIPLOPODA. 



Julus moreleti Lucas. 

 Julus hermudanus, sp. nov. 

 Julus nesophilus, sp. nov. 

 Rhinocricus monilicornis (Porath). 

 Rhinocricus ectus, sp. nov. 

 Microspirobolus excursans, sp. nov. 

 Orlhomorpha coarctata (Saussure). 

 Strongylosoma guerinii (Gervais). 



CHILOPODA. 



Scolopendra subspinipes Leach. 

 Mecistocephaliis maxillaris Gervais. 

 Hydroschendyla submarina (Grube). 

 Lamyctinus cceculus (Brolemann). 

 Lithobius provocator (Pocock). 

 Tidabius navigans (Chamberlin). 

 Scutigera coleoptrata (Linne). 



Of these species three of the chilopods and one of the diplo- 

 pods occur in the warmer parts of the entire world, these tropi- 

 copolitan forms being Orthomorpha coarctata, Scolopendra sub- 

 spinipes, Mecistocephalus maxillaris, and Lamyctinus caeculus. 

 Of the remaining species it is rather surprising to find that only 

 one, namely Rhinocricus monilicornis , occurs also in the West 

 Indies, though it is quite possible that the other Rhinocricus and 

 the Microspirobolus may with further exploration be found 

 there, the present evidence being, however, that they are 

 indigenous. In fact, four out of the six genera represented 

 by the remaining species — Lithobius, Tidabius, Hydroschendyla
