MARINE MOLLUSCA OF QUEENSLAISTD. 343 



TJ . dussumieri and U. arcuata, but at Cooktown U. mai-ionis, var. 

 nitida. Another burrowing crab is Sesarnia hidens. The active 

 Metopograpsus messor darts over the ground and chmbs among the 

 roots. The hermit crabs are numerous among the mangroves. Far 

 above the tide mark swarm Coenobita ; C. spinosa, var. olivieri, and 

 C. rugosa. Globose shells, such as Neritma and Natica, are th«j 

 favom-ite apartment for Clihanarius virescens, while C. padavensis is 

 pai'tial to the more elongate Telescopium shells. 



High up among the mangrove branches roost several marine 

 molluscs of the genera Litorina, Cerithidea, &c. On the roots clust&r 

 the oyster, and here will be detected by some conchologist more foi'- 

 tunate than myself the strange Enigma (enigmatica. Among the 

 loots crawl a variety of gasteropods, ranging downward in size from 

 the great Telescopium and its relations of the Cerithiidte. The 

 Auriculacea Nerita, Ondiidium and Stenothyra, are characteristic of 

 this zone. The large Cyrena is a common form; Lucina corrugata 

 and some of the Tellinidae represent the bivalves. 



In conclusion, I will express the hopes that the study of the 

 Marine Faima will not be left to visitors and foreigners, but that 

 Queensland's own children Avill take up this fascinating subject; that 

 their Biological Station may be soon established ; that the Queensland 

 ^Museum may be enlarged and more liberally endowed ; and that from 

 the promised university there may flow an ever-increasing stream of 

 knowleds'e. 



APPENDIX. 



CATALOGUE OF THE MARINE MOLLUSCA OF QUEEXSLAXD. 



Xo Catalogue of the Marine ^loHusca of Queensland has yet been com- 

 piled. The following list is merely preliminary, and any serious effort would 

 greatly enlarge it. In 1888 Professor Tate estimated the marine moUusca 

 from tropica] Aiistralia at 1.500; now more than 1,800 are known from 

 Queensland alone. But Hidalgo calculates the marine mohuscM of the Philippine 

 Archipelago at over 3,000. The marine mollusca of the Japanese Empire 

 amount to nearly as many. The fauna of tlie Australian tropics will probably 

 prove comparable with these. 



The addition of the author, date and original genus to the name, will 

 enable students to recover the original description at a single consultation. 

 Sherborn's invaluable Index Animalium is the readiest means of tracing the 

 older species. If eai'lier than 1835, Deshayes' edition of the' Animaux sans 

 vertebres will probably contain the species. If the date be later than 1864, the 

 Zoological Record will be tlie most convenient guide. Between 1835 and 1864 

 most entries may be found in the decennial indexes of the Zoological Society's 

 Proceedings. Sykes' Digesta jNIalacologia may also be consulted with ad- 

 vantage.
