The above list by no means includes all the species obtained, 
there are many more which require identifying, but time does 
not admit of them being dealt with at present. 
The Polyzoa obtained are very interesting, inasmuch as there 
are amongst them many of the species lately described as new by 
Mr. A Waters, and others described by the late Rev. J. E. 
Tenison-Woods, the whole of which are additions to the collection. 
Selenaria punctata, Ten. -Woods, and S. concinna, Ten.AV oods, 
were obtained in quantity and in good condition, no doubt many 
of them were alive when caught in the dredge, but owing to 
the subsequent washing and drying the vibracular organs were 
destroyed. Amathia lendigeri , Linn., is recorded from Port Phillip, 
but has not previously been observed in Port Jackson. 
Among the Crustacea two species are worthy of notice : 
Paramithrax peroni, M. Edwards (new to our local fauna), and 
Dromia sculpta, Haswell, a rare and interesting species. The 
specimens obtained have enabled me to settle the question 
regarding the identity of Cryptodromia nodulifera , Henderson, 
described in Vol. xxvii. of the “Challenger Report” with Dromia 
sculpta , Haswell. After a careful examination of the type and a 
dozen other specimens, \ cannot see any valid reason why they 
should be regarded as distinct; the specimens exhibit a considerable 
amount of variation in the number and size of the nodules, and in 
the areolation of the surface of the carapace ; in the female and 
in young males the regions are ill-defined, but in adult males 
the regional depressions are well marked. The “ Challenger 
specimens are evidently immature as the following measurements 
will show ; (1) Adult male — length of carapace 12 mm., breadth 
13 mm. ; (2) adult female — length 9 mm., breadth 11 mm. 
The two Cirripedes obtained were both interesting, Balanus 
triyonus , Darwin, on account of its being full of ova, a fact worth 
recording, as little is known regarding the breeding season of our 
Cirripedes ; the vitality exhibited by this species is remarkable, 
some hundreds were obtained attached to the branch of a tree ; 
after being out of water for two days the branch was soaked in
