PERACARIDA (MVS/DACEA) AND EUCARIDA (^DECAPODA") 8i 



a light magenta, or spotted with this colour on the dorsum, the 

 antenn?e being speckled and the eye-stalks red ; some, both large 

 and small, are green, or mauve striped with white, from the rostrum 

 half way backward, then merging into dots and disappearing, or 

 , green similarly striped on the back. A few are striped with grey and 

 translucent greenish bands alternately, with brown markings, the 

 anterior third of the tail translucent, the rest dark brown. No form 

 could better illustrate Nature's camouflage. They swim with great 

 rapidity, darting here and there and dexterously avoiding the forceps 

 hiding under the broad fronds of Lamhiaria saccharina, and even 

 leaping out of the water when closely pursued. 



Spirontocaris pusiola, Kroyer. In this, and others allied, the 

 lower terminal spine of the rostrum is longest. The telson has four 

 sets of small spines, but is not furnished with hairs at the tip. It has 

 two strong lateral bristles and some smaller central. Dr Howden of 

 Montrose, who found it in the Forth, may have included two small 

 spikes close to the long spines of the tail as making his five spines, 

 for it is doubtful if any have five spines in the telson. They are 

 spotted with reddish pink here and there, but this does not interfere 

 with their general light hue. The legs are banded across by the 

 same light magenta or reddish pink. Their motions in the water are 

 graceful, and they keep the elevated antennules in a continual 

 tremor, whilst the antennae are chiefly borne laterally. 



Doryphorus gordoni, Bate. The rostrum has six teeth above, 

 a large upper one at the tip and a smaller below, and it is not in- 

 curved at the base. In the second pair of feet the wrist has only 

 two joints and the hand is much enlarged. The telson has but three 

 pairs of minute spines, whilst the tip has four long spines, the two 

 outer lonsest.

Nephrops norvegicus, L. Bell states that its colour is generally 

 " pale flesh, rather darker in parts, the pubescence light brown " ; but 

 this chiefly applies to examples in spirit. The chelipods have their 

 upper surface of a bright scarlet, enlivened by the white points of 

 some of the tubercles, and the under surface has also much scarlet. 

 The dorsum of the abdomen and the walking legs have various shades 

 of red. The ovigerous females are generally small. 



Homarus gamfiiarus, L. The examples from St Andrews 

 usually have five teeth on each side of the rostrum, four being the 

 number mentioned by Bell, who notes the presence of two small 

 teeth at the base of the rostrum, but he omits them in Galathea. 

 The smallest example was one four inches long, tossed on shore by 

 89 AND 90 L
