and Scyllarides, so much so that one is inclined to regard them as very closely related. In 1949* 

 I described and figured a phyllosoma from Bermuda which I attributed to Scyllarides sp., stage I. 

 Although like Scyllaris, in many ways it was more developed, especially the antennae which were 

 segmented and branched, the telson also being much more advanced. In many ways it resembled 

 Jasus which has not been recorded from Bermuda, but the telson of Jasus is different and the antennae 

 reach beyond the eyes, the two branches being much longer. The third leg is also much longer, the 

 thorax broader than long (in the Bermuda species it is pear-shaped and longer than broad). At least 

 two species of Scyllarides occur in Bermuda and it is probable that my S. phyllosoma B belongs to one 

 of these. The similarity to the Jasus larva is, however, very striking. 



Gurney's later stage of Jasus was 11 mm. long and was about stage VIII (Gurney, 1936, p. 421). 

 He suggested that his specimen was about six weeks old. It was captured at a depth of 200-0 m. 

 One of Gurney's specimens of this size was taken 900 miles from the nearest coast. The present 

 specimen came from 93 miles off-shore (Fig. 3). 



Anomura 

 Paguridea 

 Paguridae 

 Three species of pagurid larvae occur in the collection. The first represented by one damaged specimen 

 only is of the Eupagurus type and is in the second stage (St. WS 1001, 50-0 m.). The second is repre- 

 sented by two larvae of the Glaucothoe peronii Milne-Edwards type (see Gurney, 1942, p. 259) 

 (St. WS 997, 1000-0 m.). 



It has been suggested by Bouvier (1905) and Thompson (1943) that these large Glaucothoes belong 

 to the genus Sympagurus, the larva agreeing in many ways with the adult of this genus. It is probable 

 that it belongs to some deep-water genus and not to a shore form. 



The third larva represents a type of pagurid larva not hitherto described. Two specimens were 

 obtained from St. WS 1001, 50-0 m., two specimens from St. WS 1047, 100-0 m., and three speci- 

 mens from St. WS 1047, 100-0 m. The two last hauls were made during the second survey, the 

 material from which has not yet been fully worked out. All these larvae are in the first stage. 



One specimen only of a similar larva, but of a different species obviously closely related, was 

 obtained in one of Dr Moore's hauls in Bermuda (ioo-i5ofms.). These elongated larvae belong to some 

 pagurid, but are not at present identifiable with any known adult. They are peculiarly interesting as 

 they differ entirely from any known form and they are worth a detailed description. The drawings of 

 the Bermuda specimen were shown to the late Dr Gurney who suggested that the larva might belong 

 to one of the symmetrical genera. 



The characters which these first larva have in common are the great length, elongated body, long 

 rostrum, carapace rounded posteriorly with conspicuous grooves, antenna with a large spine at the 

 base of the exopod, the endopod with three terminal setae, abdominal somites 2-5 with long curved 

 latero-ventral spines directed backwards, telson deeply incised with the usual hair-like second seta of 

 the pagurids and their allies, rounded knobs on rostrum and carapace, and on part of the abdomen and 

 telson. 



I shall call these larvae from the Benguela Current and from Bermuda, larva A and B respectively. 



Larva A. Five specimens from the Benguela Current (Fig. 4). The colour does not show. Length 

 of body 6 mm., transverse groove on carapace definite but imperfect. Rostrum reaching well beyond 

 eyes for about twice the eye length, knobs on each side of the margin. Knobs scattered on carapace, not 

 showing much on abdomen but present near the margin of the telson. Abdominal somites 2-5 with
