the apex. The second specimen showed 21 dorsal teeth in 

 series, 1 after a long interval, and still another after a shorter 

 interval lying close to the apex, the first and second dorsal 

 teeth were behind the orbit, the twenty-first just behind the 

 foremost of the 10 ventral teeth. A third specimen bore 17 

 teeth in dorsal series, 3 of them behind the orbit, a single tooth 

 after a long interval, and after a short interval 1 tooth near the 

 apex ; the ventral teeth were 14, the foremost almost under 

 the single dorsal tooth following the long interval. The fourth 

 specimen, a female with eggs, had 16 dorsal teeth, 2 of them 

 behind the orbit, then a very long interval followed by 2 teeth 

 close to the apex, the 14 ventral teeth reaching much beyond 

 the dorsal series, but not nearly to the apex. The fifth 

 specimen, also a female with eggs, had 17 dorsal teeth 

 followed at a long interval by 2 at the apex, which was 

 approached at a shorter interval by the 13 ventral teeth. The 

 sixth specimen, a small one, had 18 dorsal teeth, of which the 

 foremost was slightly more distant from its neighbour than 

 the others and followed at a long interval by 2 at the apex, 

 with 12 ventral teeth also distant from the apex. The seventh 

 specimen differs much from the others, having a series of 

 6 teeth, 3 of them behind the orbit, followed at a short distance 

 by a series of 3 ending a little in advance of the eyes, all the 

 rest of the rostrum being devoid of teeth, except a minute 

 group below the apex. This is perhaps a monstrosity rather 

 than a variation. The first specimen measured 24-5 mm. in 

 length ; the apex of the telson carried 7 long spines, 3 on one 

 side and 4 on the other of the minute central point, flanked by 

 a short pair of lateral spines, a similar pair a little higher up 

 being unsymmetrically placed. That one of the named 

 varieties may claim these specimens for its own is not 

 unlikely.
