thrice before, and not less rare is Pseudibacus pfefferi Miers, which 

 appears to be the post-larval free-swimming form of a Kcyllarid, probably 

 Scyllarides sqmmmosus Edw. Many other interesting forms occur in 

 the collection. 



Larval Stages of Palinurus.* — E L. Bouvier gives an account of 

 the phyllosoma-stages of Palinurus vulgaris, and of the transition from 

 the phyllosoma to the puerulus. It appears that the rock-lobster does 

 not pass through the curious phyllamphion stage descri lied by Reinhardt 

 in 1858, for the puerulus comes right out of the phyllosoma. 



Larval Stage of Jaxea nocturna.f — E. L Bouvier describes the 

 Lucifer-like trachelifer stage of Jaxea nocturna, a rare Decapod, the 

 natant stage of which is still to seek. 



Male of Anthura gracilis. J — E. W. Sexton gives a full description 

 of the adult male of this Isopod. The female and young male have 

 been previously described, but not the adult male. The statocysts 

 on the telson are in general structure the same as those of Gyathura 

 described by Thienemann. Each consists of an oval vesicle, with 

 crystalline bodies forming a statolith, with a fine duct communicating 

 with the exterior, and with a strong muscle attached to the anterior 

 wall. 



Annulata. 



Studies on Polycha3ts.§ — W. C. M'Intosh discusses additions to 

 British Spionidae and Cirratulidae recorded by Southern from the 

 West Coast of Ireland ; the British Terebellidaa, describing twenty-five 

 species ; Terebellids collected by the ' Porcupine ' and the ' Knight 

 Errant'; Chaetopteridaa, Arnphictenidaa, and Ampharetidse from the 

 Gulf of St. Lawrence ; Ampharetidae and Terebellidae from off Norway ; 

 and the occurrence (186:3) of one of the Pisionidte (Macrochseta clavicomis 

 Sars) at St. Andrews. Numerous bristles and hooks are figured. 



British Marine Annelids. || — W. C. M'Intosh is to be congratulated 

 on the progress of his monograph on British Polychteta, the present 

 instalment being the first part of the third volume. It deals with the 

 families Opheliidaa, Scalibregmidaa, Sphaerodoridse, Teletlmsas, Chlorre- 

 midas, Chaetopterida?, Spionidae, Cirratulidae, Capitellidae, Maldanidae, 

 Ammocharidag, which are represented by fifty-four genera. 



Oligochseta from Northern India. % — J. Stephenson describes a 

 large number of new species mainly from Northern India. Noteworthy 

 is Enchytrmis harurami sp. n., for only one other certain species is 

 known from India. The sperm-sacs are described. The occurrence of
