sides that are attached to the coral-branches which are usually so 

 deeply imbedded that they seem to pass through the side of the case. 

 The inner surface of the case is smooth, but the outer surface is more 

 or less rough and uneven, and usually covered with a thin adherent 

 coat of greenish mud. The egg itself is much smaller than the inte- 

 rior of the case. It is covered with a firm, smooth, transparent shell. 

 The form is usually a pretty regular ellipsoid, sometimes varying 

 to ovate. The color is orange or salmon.. 



The egg-cases are from 20"^"^ to 26™™ long; 14 to 17""" broad. 

 The eggs in alcohol are 15™™ long; diameter, 12™™. Another one is 

 16™™ long ; 11"'™ in diameter. 



These eggs have been dredged at stations 2051, 2072, 2205, 2209, 

 2210, 2212, and in other localities, in 428 to 1,106 fathoms.

Shell rather large, elongated fusiform, with a tall, acute, turreted 

 spire, consisting of about seven whorls besides the nucleus, which 

 contains about four brown whorls. The whorls have a rather con- 

 spicuous shoulder, below w'hich they are flattened, but above it they 

 have a broad, sloping, decidedly concave, subsutural band. The 

 suture is distinct, but not at all impressed, owing to the flattening of 

 the whorls. The sculpture consists of a row of prominent, oblique, 

 elongated nodules at the shoulder ; those on the upper whorls rela- 

 tively more prominent and angular than on the lower ones; these 

 nodules ai"e continued downward in the form of slightly raised, 

 obliquely curved ribs, which extend nearly across the upper whorls, 

 but fade out a short distance below the suture on the lower ones. 

 The whorls are also crossed by distinct lines of growth which curve 

 strongly forward on the middle of the last whorl and recede in a 

 strong regular curve on the subsutural band, where they are numerous 

 and fine, but on the upper whorls part of them become more promi- 

 nent near the suture. The whorls below the shoulder are also cov- 

 ered with numerous, impressed, regular, revolving grooves, separated 

 by intervals of somewhat greater width ; these revolving furrows are 

 crossed by the lines of growth in such a way as to make them wavy 

 or crinkled. The revolving lines are mostly absent above the
