Occurrence. This species was taken by the "Ingolf" at a single station. 



Southern Part of Davis Straits: St. 36, 6i°5o'N. L., 56°2i'W. L., 1435 fm., temp. 1-5°; 1 spec. 



Distribution. A. Milne-Edwards & Bouvier note the species from two points north of the 

 Azores at 42 15' N. L. and 42° 19' N. L. where the depth was 2114 and 2133 fm. In the "Challenger" 

 the species is noted from west of Valparaiso, 1375 fathoms and S. W. of Australia, 1800 fm. 



Remarks. My single specimen, a female, has been compared both with the descriptions of 

 A. Milne-Edwards & Bouvier and with a co-type from the Paris Museum. My specimen differs only 

 in .that the rostrum is somewhat longer, the spine on the outer corner of the second antennal segment 

 longer and more pointed, reaching out a little past the centre of the outer margin of the following 

 joint, and lastly in that it has four pairs of spines on the gastric area. In all other respects, viz. 

 antennules, eyes, granulation on the thorax, spines and granulation on the legs, it agrees with the 

 description and the Paris specimen. Concerning the rostrum it may be remarked that, according to 

 the measurements of the French authors, this was 14-5 mm. long in a female in which the cephalothorax 

 with rostrum was 45 mm., that is, scarcely a third of the latter length; in my specimen the cephalo- 

 thorax with rostrum is 26 mm., the much upward curved rostrum S'S mm., thus a little over a third 

 of the whole length. For the rest, my figures of the cephalothorax will show the details in the spiny 

 armature.

Occurrence. This species has been taken once by the "Ingolf". 



West of Iceland (halfway between Iceland and Greenland): St. n: 64 34' N. L., 3i°i2'W. L., 

 1300 fm., temp. i-6°; 1 spec. 



Distribution. M. similis was founded on a specimen taken off the east coast of America at 

 39 46'// N. L. in 1060 fm.; M. crassa Smith, to which M. similis appears to belong as a variety, was 

 founded on a specimen taken off the east coast of America at 36 i6 I / 2 ' N. L., in 2574 fm. There is also 

 considerable probability that Munidopsis subsquamosa var. aculeata Hend. belongs to M. crassa -(- 

 .]/. similis and this form was taken by the "Challenger" west of Patagonia, 1450 fm. and "between 

 Marion Island and the Crozets", 1375 fm.
