others. The claws are in pairs, united at the bases only. One claw of each pair is 

 larger. No supplementary points were seen. There are no eye-spots. 



The pharynx is 40 /* long by 30 /u wide. Having points of affinity with several 

 species (M. echinogenitus, M. areolatus, &c.), the recognition of the egg is necessary for 

 its identification. The strong comma distinguishes it from areolatus, but, as Richters 

 has pointed out, we are not yet sure of the constancy of the "comma." The slight 

 shortening of the middle rod may show some degree of relationship to M. virgatus, a 

 Canadian species (see p. 173 and Plate XXI. Fig. 55). 



HAWAII: ISLAND OF OAHU 



Collecting in Ilaivaii. At Honolulu we remained for twenty-four hours, so that 

 there was a much better opportunity for collecting than we had in Fiji. As, how- 

 ever, we arrived at 5 P.M. it was impossible to get clear of the town before sunset, 

 and serious collecting had to be deferred till next day. The remaining daylight of 

 the first evening was occupied in making a journey by street-car to the Aquarium. 

 On the way some irrigation ditches were seen, and these were visited, and a net 

 thrown in to collect the aquatic rotifers, with lively hopes of getting Trochosphcera, 

 and who knows what else ? A few sweeps of the net filled it with a delightful green 

 slime, of endless possibilities, but alas ! in drawing it out it caught on some spiny 

 twig and was torn, and the contents lost. 



Next day a start was made in the cool of the morning, before sunrise. Even at 

 that early hour (5 A.M.) a cafe was found open, and by the time breakfast was over 

 the street-cars were running. Knowing nothing of the geography of the country, an 

 electric tram was boarded, which, as luck would have it, conveyed me five miles out, 

 to the foot of a valley on the east of the city. For a mile or two the road ran 

 through the level valley, among farms. A very little stream ran in this valley. It 

 would be only two or three feet across and a few inches deep. None of the water 

 was wasted, each farm or garden using it for irrigation, and letting the overflow pass 

 on to the next. No mosses were seen in this valley till the last of the houses was 

 left behind, when some tufts growing on clay were got on the banks of the stream. 



The stream was now left and I began to climb up a long spur rising gradually 

 towards a ridge which formed the watershed at the head of the valley. The country 

 was open, with deep grass and occasional bushes. Here, at some little elevation, 

 moss of a likely kind began to appear, first on stones, then on the stems of trees and 

 bushes. Everything was dry and scorched by the sun. 



As I advanced the bushes became denser and rather troublesome. The moss also 

 became quite abundant and my pockets were bulging with it. There were many 

 kinds of it, but one was dominant. It formed large sheets of a vivid green, with 

 rich autumnal browns in the withered parts. It had all the habit of a pleurocarpous
