politan distribution. It lias been captured most often in the north Atlantic, both on the east 

 and west side, as far northward as Davis Strait and Iceland, the variety acanthiielsotus, with 

 which Coutiere's variety multispitia is identical, has been observed, both by the Challenger 

 and the German Southpolar-Expedition, in the tropical Atlantic, while the typical species was 

 taken by the same expeditions at various localities of the south Atlantic. This species has also 

 been observed in the Mediterranean, recently also in the Adriatic and has been recorded from 

 Cape Point Lighthouse, South Africa, under the name of Acanth. batei. It was taken by the 

 Percy Sladen Trust Expedition N. of Chagos Archipelago and S. by E. of Farquhar, but it 

 does probably not occur in the more northern parts of the Indian Ocean, being here replaced 

 by the closely allied Acaiith. sanguinea W.-Mas. ; specimens of this species, finally, have been 

 captured by the "Challenger" off Banda Island in the Indian Archipelago and off the coasts 

 of Australia, New Zealand, the Kermadec Islands and Japan, while two specimens were taken 

 by the "Albatross" in the Gulf of Panama: a world-wide distribution indeed.

No less than nine fine and well-preserved specimens of this apparently rare species were 

 collected, both in the western and the eastern part of the Archipelago, among which are 

 three adult ova-bearing females: they belong all to the typical species, described by A. Milne- 

 Edwards, not to the variety fimbriata W.-Mas., that occurs in the Arabian Sea and the Bay 

 of Bengal. The male from -Stat. 161 is 165 mm. long, the carapace, measured between the 

 orbital and posterior margins, 38 mm., the rostrum, measured in a straight line from the orbital 

 margin to the apex, 33 mm., the abdomen 94 mm.; the ova-bearing females are 170 — i7Smm. 

 long, the carapace of the largest female, one from Stat. 262, measuring 38 mm., the rostrum 

 34,5 mm., the abdomen 105 mm. In these four adult specimens the rostrum is distinctly shorter 

 than the carapace, in the larger male, long 147 mm., from .Stat. 173 also still a little shorter, 

 in the other male, long 135 mm., from the same Station the rostrum appears as long as the 

 carapace and in the three males from Stat. 314, that are about of the same size as those 

 from Stat. 173, it appears in one just as long as the carapace, in the two other ones, however, 

 distinctly longer than it. In the adult male from Stat. 161 the teeth at the extreme proximal
