dactylar teeth, for the specimens which I^anchester records from Penang, and which 

 also were only 75 inches in length, possess twelve to fourteen teeth. It is, however, 

 not impossible that the post-larval development of the species may vary in different 

 localities. 



The two examples of L. spinosa in the Indian Museum were found at the following 

 localities : — 



^p Port Blair, Andamans. . . J. Wood-Mason. . . 1 2 , 68 mm. TYPE. 



~ Dunedin, New Zealand. . . F. W. Hutton. . . 1 9 , 74 mm. 



The species has been recorded from numerous localities in New Zealand and in 

 the neighbouring islands : Chatham Is., Kapiti and Waikanae, near Wellington 

 (Kirk), Waipapa Pt. and Port Pegasus, Stewart I. (Thomson), Port Chalmers, Otago 

 Harbour, Resolution I. (Chilton), Napier District (Hamilton) and Auckland Is., in the 

 stomach of Notothenia microlepidota (Hutton). In addition it was found by Sir J. C. 

 Ross' Antarctic Expedition (Miers) and is known from Penang (Iyanchester). Accord- 

 ing to Chilton most of the specimens which have been recorded were taken from the 

 stomachs of fish.

 The dorsal surface is smooth and polished. The greatest breadth of the carapace 

 is about equal to its mid-dorsal length ; for the rest, it bears a close resemblance to that 

 of L. maculata. The rostrum is widest at the base and is usually a little longer than its 

 greatest breadth. It terminates in a slender median spine and possesses in addition 

 prominent antero-lateral angles on either side. These are rectangular or slightly obtuse, 

 and the margin both before and behind them is concave : the former more strongly 

 so than the latter. The rostrum is thus composed of an almost square proximal portion 

 which bears at its distal end a sharp spine with a very broad base. 



The eyes are composed of two closely- approximated lobes. The greatest breadth 

 of the cornea is about equal to the greatest length of the stalk. The anterior edge of the 

 ophthalmic somite is rounded, but, when the animal is viewed from above, is entirely 

 concealed by the rostral plate, as are also the dorsal processes of the same somite. The 

 antennular peduncle is less than half the length of the carapace excluding the rostrum. 

 The dorsal processes of the antennular somite consist of two long and sharp spines 

 directed obliquely outwards and forwards and reaching to the middle of the eyes. The 

 mandibular palp is composed of three segments.
