There remain i \v<> specimens, apparently of tins genus, from the New Zealand 

 waters, belonging evidently to two distinct sprrirs : but as io rlic determination of 

 these I prefer to reserve judgment. I hesitate to found a new species upon a single 

 specimen, as the description must necessarily lie incomplete, and mav only lead to 

 confusion. One of these two individuals, which I will call L\tn-nx s p. " A." is interesting 

 mainly <m account of the following features: The liody is slightly flattened, and the 

 head is shaped like an arrow-head, the posterior ends of the cephalic slits projecting 

 considerably at the sides, and the snout tapering to a point. The cephalic slits are 

 ;!'.") mm. long. Tin 1 mouth is small, and measures only slightly over '2 mm. in length. 

 The skin is deeply pigmented, of a rather dark olive-green colour. The pigment - 

 granules are closely crowded together in the thick primary basement-membrane, and in 

 another layer immediately outside the circular muscle-layer of the body-wall. Between 

 these two main layers scattered granules are also seeu in the radiating strands of 

 connective tissue among the outer longitudinal muscles. The snout, and the edges 

 of the cephalic slits and mouth, are ochreous, and may perhaps have been red during 

 life. [Length of specimen (tailless). 5 cm.]

There is a single very small specimen in the collection, with a minute tail-like 

 appendage at the posterior end. The total length of the animal is about 7 mm. The 

 skin is transversely wrinkled, and the general colour yellowish, thickly dotted with 

 minute reddish-brown spots of pigment. 



The snout is thick and square, and the whole head large in proportion to the 

 body. The cephalic slits measure a little over 1 mm. in length. The mouth is 

 elongate, but not large, and lies behind the cephalic slits. 



It is only provisionally that I assign this specimen to the genus ( 'ert'lirntiilu*. and 

 I regard it as probably a very young individual.
