Chilton. — Notes on the Callianassidas of N.Z. 459 



on the abdomen or telson of G. hirtifrons, White ; indeed, the 

 telson may be marked by a narrow depressed median hne. 



In making the comparisons quoted above Miers appears to 

 have been relying on the type specimen of G. hirtifrons, White, 

 in the British Museum ; Mr. Haswell's specimens from sponges 

 at Port Jackson, as already stated, do not belong to White's 

 species. I am indebted to the trustees of the Australian Museum 

 for several specimens from Port Jackson, and they are certainly 

 quite distinct from White's species, being easily distinguished, 

 in addition to other points of difEerence, by the fingers of the 

 chelipeds being subequal and the chelipeds therefore perfectly 

 chelate, so that the species comes under the genus or subgenus 

 Gehiopsis as defined by A. Milne-Edwards ; the authorities of 

 the Australian Museum consider the specimens as probably 

 belonging to Gehiopsis bowerhankii, Miers. 



Mr. Stebbing has directed attention to the character of the 

 1st pleopods in the genus Upogebia as previously described by 

 De Haan and Boas — viz., that in the male these appendages 

 are absent, while in the female they are present but quite dif- 

 ferent from the four following pairs (see " South African Crus- 

 tacea," part i, p. 45). This is also true of my specimens, the 

 Kenepuru specimen being a male with the 1st pleopods absent, 

 the other two being females with small uniramous 1st pleopods. 

 The one from Auckland Harbour bears eggs : these are attached 

 to the small 1st pleopod, to the inner branch of the 2nd, and 

 to both branches of the 3rd and 4th pleopods. 



Mr. J. Macmahon, to whom I have been indebted for various 

 specimens of Crustacea at different times, thus describes the 

 capture of the Kenepuru specimen. It was, he says, " taken 

 alive at the entrance of a hole about half an inch wide in sand 

 near low-tide mark ; this hole was well formed, and went some 

 depth into the sand, over which fresh water ran on its way to 

 the sea, much of it percolating down the hole."

Specific Diagnosis. — Cephalothorax about two-thirds the 

 length of the abdomen ; the front distinctly trilobed, lobes 

 triangular, acute, middle one the largest ; the scabrous portion 

 of the front not reaching half-way to the cervical groove, except 

 the lines of minute spines extending backwards from the outer
