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 jniiictata, Ten. -Woods, and S. concinna, Ten. -Woods, 

 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 previousiy been observed in Port Jackson. 



Among the Crustacea two species are woi'thy 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 

 regai'ding tlie identity of Crypiodrotaia nodul'tfera, Henderson, 

 described in Vol. xxvii. of the " Challenger Report " with Droraia 

 scidpta, Haswell. After a careful examination of the type and a 

 dozen other specimens, I 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-detined, 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 nmi., breadth 

 13 mm. ; (2) adult female — length 9 mm., breadth 11 mm. 



The two Cirripedes obtained were both interesting, Balanus 

 trigonus, 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
