black cross Lauds passing right round the body ; but, besides these, 

 there are occasionally aborted hands, the remnants of which are 

 found either as large black dorsal spots or imperfect bands on the 

 belly half. There is a black spot on the back of the neck between 

 the first hand that passes across from the angles of the month and 

 the one behind it. In every other particular this specimen differs 

 in no way from typical Il.jerdonii. 



Pooree. 



This specimen is much infected with Cirripedes and Tuhularious 

 Zoophytes, which seem to indicate that it is not of very active 

 habits.

This specimen has the third labial not in contact with nasal on 

 one side ; but on the other, throughout, the third labial is broadly 

 in contact with the nasals, as a small labial has been formed be- 

 tween the first and second, thus converting the latter into a third 

 labial. If this arrangement had occurred on both sides, it might, 

 perhaps, have given rise to another synonym for this species. 



Hydrophids are frequently cast ashore on the Pooree coast ; but 

 they soon die, even when every care is taken of them.

Head very small, not distinct from the neck, which is very long 

 and whip-like ; the slender portion of the body equals more than 

 one-third of the total length. The rostral pentagonal, as broad as 

 high, the lower margin with a median process and a concavity 

 on either side of it ; nasals oblong, with the nostrils in their poste- 

 rior half, in the angle formed by the posterior and external mar- 

 gins ; frontals longer than broad ; vertical shield-shaped, very slightly 

 smaller than a superciliary ; occipitals much elongate, rounded pos- 

 teriorly. One prseocular and one postocular ; two large temporal 

 shields alongside of the occipital. Third labial not in contact with 

 the nasal ; second labial very large ; first lower labials forming a 

 broad suture behind the mental, and succeeded by a pair of penta- 

 gonal chin-shields forming a broad suture and succeeded by a tri- 

 angular pair widely divergent behind. Scales imbricate, in twenty- 

 eight series round the neck, each with a prominent tubercle near 

 the tip. Ventral shields on the slender portion of the body twice 

 as large as the surrounding scales, smooth anteriorly, but with two 

 tubercles when they reach the thick part of the body, where they
