When first examined we regarded the specimens collected at Well- 

 fleet as distinct from Anaitis speciosa ; subsequent comparison of speci- 

 mens has shown that the former must be regarded as a variety of the 

 latter. As compared with specimens from New Jersey, these have the 

 bead a little narrower ; the anterior emargiuation of the buccal seg- 

 ment, with the corresponding backward curvature of the posterior mar- 

 gin of the head, not so well marked. 



The color is variable. In front of the eighth segment the color is 

 yellowish- white ; a dark-brown band covers the eighth segment and the 

 anterior half of the ninth ; behind this band the color is yellow or 

 brownish-yellow ; the middle third of the anterior margin of each seg- 

 ment is brown, while on the posterior segments this brown band runs 

 entirely across the segment ; the branchite for their inner two- thirds are 

 yellowish-brown, outer third white; the brown baud of the eighth and 

 ninth segments includes the branchiae, and is faintly perceptible below ; 

 body and branchiae with numerous flake-white specks ; head white with 

 brown specks ; or the general color may be white, green replacing the 



* Examination of many specimens at Eastport, Me., has fully established the iden- 

 tity of P. tecto with P. minuta.
