Six specimens from Hood and Chatham in May. Previously 

 known only from Hayti, but the specimens agree with this species 

 in all important particulars. The hand is hardly fuscous; the body 

 is pale brownish, sometimes with traces of transverse dark marks; one 

 specimen shows the region between the submedian ventral keels 

 darker than elsewhere ; there are ten full keels on segments one to 

 three ; on under side of fifth segment is a median keel, also a lateral 

 keel and a submedian keel, which latter, however, is not complete 

 but lost in the granulation of the general surface ; the tubercle under 

 the sting is very small ; the fingers show the lobe and cavity as des- 

 cribed by Karsch. The largest specimen is about 44 mm. long.
