There remain two specimens, apparently of tliis genus, from tlie New Zealand 

 waters, ])elouging evidently to two distinct species; but as to the determination of 

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

 specimen, as the description must necessarily l)e incomplete, and may only lead to 

 confusion. One of these two individuals, which I will call Linens sp. " A," is interesting 

 mainly on account of the following features : The l)ody is slightly flattened, and tlie 

 head is sluiped 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 

 3"5 mm. long. The 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 seen 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 liave lieen red dui'ing 

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

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

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

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

 minute reddish-brown spots of pigment. 



The snout is thick and s<|uare, and the whole head large in proportion to the 

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

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



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

 I regard it as prolialdy a very young individual.
