JEga Hurfordii. 



Sides of thorax almost straight, segments sub-equal. Cephalic shield 

 rounded in front, eyes conspicuous, situated at the postero-lateral angle of 

 shield. Abdominal segments five or four, last segment pointed. Exterior 

 antennae more than half the length of body, flagelluni more than twice the 

 length of base, miiny-jointed. 



Epimera of all the thoracic segments except the three first, pointed be- 

 hind, and extending further back than the segment to which they are at- 

 tached. Claws of first three pairs of legs comparatively feeble. 



Length, 0.63 in. 



Collected at Santa Rosa Island by W. G. VV. Harford, under stones at mid- 

 tide in muddy places. Numerous. 



^Ega alaskensis. 



Body broadest at 5th thoracic segmeut, sides regularly curved, 5th and 6th 

 thoracic segments greatly larger than first four thoracic segments, 7th segment 

 longer than 4th. 



Head pointed in fronted, the sides continuing the curve of the thoracic seg,- 

 ments. Epimera of 4th segment pointed posteriorly, as are also those of 5th, 

 6th and 7th thoracic segments. 



First four segments of abdomen concave posteriorly, and ending laterally in 

 a point directed backwards; 5th segment with a straight posterior margiu, 

 pointed at sides; terminal segmeut a half oval. 



Eyes large, conspicuous, not projecting. Antennae short, the outer reach- 

 ing to the suture between 1st and 2d thoracic segments; flagelluni about equa 1 

 in length to base. Last four pairs of legs somewhat spinose. 



Color (in alcohol) 4th, 5th, 6th and 7th thoracic segments dark brown, a 

 little dark brown on posterior part of 4th and 5th abdominal segments, rest 

 of body yellowish; egg-case dark brown. 



Three specimens, all females, taken from codfish caught in Ounimak Pass, 

 Alaska, lat. 54° 40', long. 165°, by Capt, T. W. Williams. 



Length of largest specimen, 1.30 inch; greatest breadth, 0.48 inch. 



Lyqia septentrionalis. 



Two posterior thoracic segments much shorter than the anterior ones, and 

 greatly curved. Caudal stylets short, about half as long as abdomen. 



Outer antennae about half as long as body, flagelluni with twelve somewhat 

 oblong joints, somewhat shorter than base. Cephalic shield with a waved, 

 somewhat two-lobed posterior margin. 



Length, without caudal stylets, 0.80 in. Width, 0.45. 



The sides, from the second to the sixth thoracic segment, are almost paral- 

 lel. Two specimeus from Tanaga, one of the Aleutian Islands, presented by 

 Mr. W. J. Fisher, naturalist of the U. S. Exploring Ship Tuscarora. 



The general facies of this species is very like L. occidentalis, but it is easily 

 distinguished by its short posterior stylets.
