. Discovery reports. Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. NARCOMEDUSAE 75 Numerous medusoid larvae were found in the canals in a specimen, 35 mm. wide, from St. 701. The sample from St. 282 contained three fragments which may possibly have belonged to one specimen of P. clara, about 15 mm. in diameter. There are altogether 48 tentacles, many of them small, partly very small, and the lappets are of very different width, most of them more than twice as long as broad and usually with two very long otoporpae. The tentacles and lappets are so densely crowded that the circumference of the medusa may very well have had the great number of 48, and I am inclined to think that the three fragments may really belong to one specimen. Four very small specimens, 3-4 mm. in diameter, were found at Stations 708 (near the coast of Brazil) and 1585 (East Africa). They have a thick and highly vaulted jelly, and also the marginal lappets are rather thick, with fairly broad canals (text-fig. 13). The lappets are as long as broad or somewhat longer, each of them with three very long otoporpae. In one of the specimens, 4 mm. wide with 10 tentacles, the otoporpae are at least twice as long as the lappets; in the three other specimens, which are 3-3-5 mm. in diameter, with 7, 8 and 9 tentacles respectively, the median otoporpa of each lappet reaches up to the very apex of the umbrella, the two others are about half as long or somewhat more, ending blindly, not connected with the median one. Text-fig. 13. Pegantha clara. A marginal lappet and two tentacles of a young specimen, diameter 3-5 mm., from St. 708, ^.p. = stomach pouch, /).c. = peripheral canal, = margin of lappet, ii. = velum. The collection contains 32 specimens, 29 of which could be measured, varying in diameter between 3 mm. and 50 mm. The number of tentacles in proportion to diameter of umbrella is summarized in the following table: No. of tentacles Average diameter (mm.
