D. 35. Osseous rings 27 + 55. 



Dorsal surface slightly convex. All parts covered with small 

 but very distinct spines ; the radiating lines of the operculum spiny. 

 Orbital edge denticulated, but without prominent tubercles above.

a-b. Thirteen inches long. Presented by Dr. Milligan. 



These specimens are evidently females, having the hinder part 

 of the body considerably elevated, much more so than in specimens 

 of the same size of S. hardwiclii. In one the length of the trunk 

 is 4^ inches, and the depth 1 inch ; in the other the proportion is as

Phvllopteryx, (Sicainson) Kaup, Lophohr. p. 20. 

 Ilaliichthys, Gray, Prvc. Zool. Soc. 1859, p. 38. 



Body compressed, or as broad as deep. Shields smooth, but 

 some or all of them are provided with prominent spines or processes 

 on the edges of the body ; some of the processes with cutaneous 

 filaments. A pair of spines on the upperside of the snout and 

 above the orbit. Tail about as long as the body, prehensile. Pec- 

 toral fins. The males carry the eggs, which are imbedded in soft 

 membrane on the lower side of the tail, without a pouch being 

 formed by a lateral expansion of the integuments (Ph. foUatus).

D. 30. Osseous rings 18 + 35. 



Trunk much elevated, especially in females, in which its depth 

 sometimes equals the length of the snout. A pair of small spines 

 on the upper part of the snout, much nearer to the eye than to its 

 extremity ; a pair of superciliary spines. A long occiintal and 

 nuchal process, which, as well as all the other processes on the 

 body, bear cutaneous appendages. Pairs of long divergent processes 

 along the back on the twelfth body-ring, and on the 1st, 10th, IGth, 

 24th, and 27th tail-rings. A similar pair of ventral processes on 

 the 9th body-ring. Scarlet or orange-coloured, with numerous 

 small round yellow spots. Each of the nine anterior body-rings 

 with a violet band on the lower half ; two or three similar bands 

 before the vent.
