LOPHOBRANCHII. M 



uncomplicated rostral crest, which does not reach to the 

 mouth. Lateral line terminating upon the anal ring. Tail 

 twice as long as the body. 



Descr. — This species has a more elongated form than the 

 preceding one. Vestiges only of lines in relief exist on the 

 temples, occiput, nape, and on the dorsal aspect of the breast- 

 rings. The broad, swollen gill-cover is striped, and has a pro- 

 minent line anteriorly. There are 15 rings anterior to the dorsal 

 fin, and 16 before the anus, as in Ich. Belcheri. The dorsal fin 

 stands on 6 rings, the first of which is the anal ring. In the 

 tail there are 36 or 37 rings in all, and 19 up to the end of the 

 egg-pouch. The following are the dimensions of a male speci- 

 men sent by Kuhl and Van Hasselt to the Leyden Museum : — 

 entire length 3 - 35 inches; length of head 0"39 inch, of body 

 1*22 inch, of tail 2 - 13 inches, of egg-pouch l - 03 inch.

Dr. Hamilton describes the colours in the following words : 

 — " The colour is greenish-brown, with some obscure pale 

 transverse belts on the back, and ten or eleven spots on each 

 side at the lower edge of the scales by which the joints are sur- 

 rounded." 



The species inhabits the Sea of Java, and specimens exist in 

 the Leyden Museum.

Diagn. — A longitudinal row of white points on the rim of the 

 belly. Belly arched and acutely keeled. 



* Dr. Hamilton enumerates 25 rays in the dorsal, and informs us 

 that the natives of India call it the " Crocodile's tooth-pick," or 

 " tooth-cleaner." He also reckons the body-rings at 32, which is 

 certainly an error, as such a number is not to be found in any species 

 of the whole subfamily. He has apparently included the tail-rings in 

 his enumeration of those of the body. 



t Dr. Bleeker has constructed his genus Hippichthys on this species 

 in the 22 band Verh. Bat. Gen. Bijdr. Ichth. Mad. p. 15, and in the 25 

 band der Verh. he renounces it. Since the name of heptagonus ex- 

 presses a form common to almost all the Syngnathida, I have chosen the 

 name of ponticerianus, previously employed in the Parisian Museum.
