Latitude 28° 36' 00" N., longitude 85° 33' 30" W., HI fathoms; station 2402, two 

 specimens (993). 



Two species of Protula have already been described from practically 

 the same region, P. media Stirapson,* and P. americana Mclntosh.t 



From these P. diomedece is readily distinguished, living as it does in 

 a comparatively straight tube attached only at the base, while they 

 both construct coil tubes attached more or less throughout their entire 

 length. A much more important difference in the case of P. media is 

 its deeply scalloped lamella? described by Stirapson and figured in Smith 

 and Harger's Saint George's Banks Predgiugs, i)l. vi, as compared with 

 the entire margin of the thoracic lamelUe of P. diomedew. In the case 

 of Protula americana the uncini are very different. Compare fig. 2 with 

 fig. 7 of Mcintosh.
