Chilton. -O/J New Zealand Squillida". 59 



Squilla ncpa is, according to Miers/- widely distributed in 

 the Indo-Pacific region, and has also been recorded from 

 Sydney and from Chili. Gonodactyhts trispinosns is known 

 from Western Australia, Fiji, &c. 



Since the publication of Miers's New Zealand Catalogue,, 

 the additions to our knowledge of the New Zealand S(piillid(e 

 have been as follows : In 1878 Mr. T. W. Kirk described as 

 a new species Squilla indefensa, from Chatham Islands and 

 Kapiti, and also recorded the occurrence of Squilla armata, 

 M.-Edw., in Wellington Harbour. In the same year Pro- 

 fessor Hutton described as a new species Squilla hevis, from 

 the Auckland Islands. In 1880 Mi-. E. J. Miers identified 

 Squilla indefensa, Kirk, with Coronis spi)iosa, Wood-Mason, 

 under the name Lysio^quilla spinosa ; but at the time of 

 writing his paper " On the Squill idee " had evidently not seen 

 Professor Hutton's description of Squilla Icsvis. In 1881 Mr. 

 G. M. Thomson described as a new species Squilla tridantata, 

 from Stewart Island. Brooks's " Eeport on the ' Challenger ' 

 Stomatopoda," published in 1886, added greatly to our general 

 knowledge of the group, and especially of the larval forms, and 

 in this respect largely completed the working-out of the 

 larval history tliat had been commenced by Claus in his " Die 

 Metamorphose der Squilliden," which appeared in 1871. The 

 number of adult forms in the "Challenger" collections was, 

 however, small, and none of them were from New Zealand. It 

 is to be noted, however, that Brooks places Gonodacti/lus 

 trisj^inosus, White, in a new genus, Protosquilla, formed to 

 include some new species and some previously put down to 

 Gonodactijlus. 



I am not acquainted with any other papers bearing on the 

 New Zealand Squilliden. 



During this year I received two very fine specimens of a 

 Squilla from Mr. W. M. Innes, of Port Chalmers, and, 

 in working these out and comparing them with the descrip- 

 tions of the different species described from New Zealand, 

 I became convinced that Squilla indefensa, Kirk, S. Icevis, 

 Hutton, and S. tridentata, Thomson, represent but one 

 species, and that my specimens also belong to this species ; 

 and it is chiefly with the object of establishing this 

 fact that I am writing the present paper, as in any 

 consideration bearing on the New Zealand fauna the ap- 

 parent existence of three species of Squilla (instead of 

 one, as is really the case) might easily lead to wrong con- 

 clusions. 



Our list of New Zealand Squillidce will therefore be as- 

 follows : —
