LOPHOBKANCHII. (il 



Dimensions of 9 : — Head 0'91 inch, snout - 59 inch, body 

 1? 7- inches, dorsal 0(>7 inches, tail 1*58 inch. 



Two pairs of males and females from -Madagascar. 



A larger male from the Isle of liourbon has only whitish points 

 on the scales that project over the egg-pouch. The ground- 

 colour is blackish-brown. The gill-cover has a golden lustre. 

 In one specimen I noticed a silvery longitudinal stripe on the 

 back, but this is probably merely accidental.

9. Doryichthys aculeatus, Cray. 



Diagn.— Edges of the body toothed ; 20 body-rings ; 17 rings 

 before the dorsal fin, which stands upon 8, of which three 

 belong to the body. Caudal rings 24. 



Descr. — The specimen which exists in the British Museum, in 

 a very mutilated condition, came from Egvpt, and was the gift 

 of Dr. John E. Gray. The snout is toothed. Head (V89 inch 

 long, snout 053 inch, body 261 inches, tail 1*93 inch. 



Genus 4. EEMITHYLACTJS, Kp. 



Diagn.— The snout, having a length exceeding that of the 

 body, has on its dorsal aspect a two-edged border, whose 

 under part is rounded. The body is compressed. 



Descr. — Head finely shagreened, without a crest. Length of 

 the snout from the middle of the eye equal to that of the head. 

 The fins are not much developed, with the exception of the dorsal, 

 which is very long. In the males an egg-pouch extends from the 

 breast-ring to the anus. At the last ring of the pectoral fin the 

 edge of the concave back unites with the caudal edge, but a 

 branch running near the dorsal fin extends to the anal ring. In 

 age each ring has a scar near its dorsal border, and one also on 

 the indistinct under-border of the tail-rings. On the indeter- 

 minate lateral line there are also scars which descend to the 

 anal ring.
