has assigned to it a South Australian habitat ; indeed, our 

 knowledge o£ the existence of representatives o£ the family 

 off the whole of the south coast of the continent is limited to 

 Squilla miles — a Victorian example of which is in the British 

 Museum. Under these circumstances it is with much satisfac- 

 tion that I have to report the presence of three species in our 

 much-neglected field of carcinographical research. 



These species are, moreover, diagnostically unknown, and I 

 propose to describe them under the names of Squilla pectinataj 

 S. ino7mata, and S. suhfasciata. They agree in one character, 

 namely, that the anterior margin of the penultimate joint of 

 the raptorial limb is furnished throughout its whole length 

 with close-set comb-like teeth. This character is entirely 

 foreign to the genus, though present in Chloridella and some 

 species of Lysiosquilla. My S. suhfaseiata makes some approach 

 to Chloridella, but the generic characters are those proper to 

 8g[uilla. 



Following the analytical scheme of Mr. Miers, I have in the 

 subjoined schedule brought the three South Australian species 

 into correlation with others of the genus. 



A. Exposed thoracic and first five abdominal segments, with 

 submedian carinap on the dorsal surface. 



I. Penultimate joint of the raptorial limbs without a 

 series of immobile spines. 



II. Penultimate joint of the raptorial limbs with immo- 

 bile spines (or denticulations) along its whole length. 



* Armature of penultimate joint spinous, as in 

 S. rapliidea. 



** Armature of penultimate joint consisting of 

 denticles, in addition to the mobile spines. 



1. Dactyli of raptorial limbs armed with 

 four spines ; antero-lateral angles of 

 carapace rounded ... ... S. pectinata 



2. Dactyli of raptorial limbs with six 

 spines; antero-lateral angles of carapace 

 spinous ... ... ... ... S. inornata 



B. Exposed thoracic and first five abdominal segments with 

 the dorsal surface smooth. 



I. Dactyli of raptorial limbs with six spines; antero- 

 lateral angles of carapace spinous. 



1. Penultimate joint of the raptorial limbs 

 without immobile spines ... ... S.fasciata 



2. Penultimate joint of the raptorial limbs 

 margined with close-set denticles ... S. suhfasciata
