Mr. E. J. Miers on the Squillidte. 125 



Squillidaj occur — Lysiosquilla acanthocarpus , L. maculata, 

 Squilla nepa, and S. raphidea, all from Penang, collected by 

 Dr. Cantor. The first mentioned is of especial interest, as 

 but a single specimen, from Port Essington, Australia, previ- 

 ously existed in the collection of the British Museum. A close 

 examination of the types of L. acanthocarpus and L. spinosa 

 (L. tricarinata), which are dried and not in good condition, 

 now convinces me that these species approach L. Brazieri in 

 having the appendage of the antepenultimate joint of the last 

 pair of legs less dilated than those of the two preceding pairs. 

 As, however, Latreille, Kessler, and De Haan, in their figures 

 and descriptions of L. scolopendra, L. eusebia, andZ. latifrons, 

 represent the appendages of all the legs as equally dilated, 

 this character cannot be supposed to be constant in all the 

 species referable to Latreille's old genus Ooronis (sect. 2 of 

 my Lysiosquilla) ; nor, on the other hand, can it be sexual, 

 as the type specimen of L. Brazieri is a female, and the speci- 

 men of L. spinosa in the Museum collection a male. In L. 

 acanthocarpus there are five, not six, spines on the upper 

 surface of the terminal segment. 



Lysiosquilla spinosa. — I have received from Mr. T. W. 

 Kirk, of the Colonial Museum, Wellington, New Zealand, 

 copies of his recently published " Additions to the Carcino- 

 logical Fauna of New Zealand," and " Notes on some New- 

 Zealand Crustaceans." In the former paper is a figure of his 

 Squilla indefensa, which leaves me in little doubt that I was 

 right in regarding this species as identical with Lysiosquilla 

 spinosa, the diagnosis of which Mr. Kirk had probably no 

 opportunity of referring to. In the second paper the occur- 

 rence of Squilla armata in Wellington Harbour is recorded. 



Of special interest, as relating to the distribution of the 

 marine Crustacea, is the discovery by Mr. Kirk of several 

 northern and arctic species (Calocaris Macandreo?, Portunus 

 pusillus, Ebalia tumefacta, Podocerus cylindricus, Pleustes 

 panoplies, and Caprella lobata) in the New-Zealand seas. 



If these identifications have been made from the descriptions 

 only, and not from the comparison of actual specimens, I 

 should hesitate to believe in the coexistence of so many species 

 not yet recorded from intermediate localities in regions so 

 widely separated. 



The occurrence of closely allied species in the northern and 

 southern hemisphere is not uncommon ; but with very few ex- 

 ceptions {Pinnotheres pisum, Lysianassa magellanica) the 

 species hitherto known to occur at once in the northern and 

 southern hemispheres are such as have an almost cosmopo- 

 litan range.
