Plate II. 



With the aid o£ Mr. Mier's* " Eevision of the Genera and 

 Species of the Sqiiillidse," I have undertaken with some con- 

 fidence an examination of the Australian species preserved in 

 the South Australian Museum. These are, with one exception 

 {Gonoclactylus graj)liurus, from Edgecombe Bay, Queensland), 

 from the tropical and extra-tropical waters of our province, 

 and are as follows : — 



Species feom the ]N"oKTnEKX Tereitory. 

 1. — Squilla raphidea, Fahricius. 

 The only example in the collection, which is from the 

 Northern Territory (probably Port Darwin), I have identified 

 with S. harpacc, De Haan,t placed by Mr. Miers as synonymic 

 with the Fabrician species here named. S. raphidea has 

 hitherto been unrecorded for Australia, though it is known 

 from various parts of the Indo-Pacific region. The Port 

 Darwin specimen measures 7i inches in length. 



2. — Gonodactylus chiragra, Fahricius. 

 Many examples from the Northern Territory, probably Port 

 Darwin, whence I have seen several specimens in the collection 

 of Mr. W. T. Bednall, by whom the}' were taken. 



3. — Gonodactylus graphurus, White. 



Two examples from the Northern Territor}', probably Port 

 Darwin. 



The following are also known from Port Essington : — 

 Lysiosqiiilla acantliocarpus , Miers ; ChJorideUa microphtlialma, 

 M.-Edw. ; and Squilla scorpio, Latreille. 



Species feom SorTii Australia. 

 Mr. Haswell had evidently not been aware of the occurence 

 of any member of the Squilla family in South Australian 

 waters, as in his "Australian Crustacea" not one of the species
