nyctiphanes norvegica was taken 10 miles W. of Duddon 

 Buoy, on February 24th, and 15 miles S.W. of 

 Morecambe Bay Lightship, on February 26th. 



Mysidacea. — Gastrosaccus spinifer was taken in 

 large numbers in Eed Wharf Bay on December 5th, after 

 sunset. One specimen of Anchialina agilis was taken in 

 Carnarvon Bay on January 20th. This is the first time 

 this species has been found in our district. One 

 specimen of Siriella armata was taken in Luce Bay on 

 October 22nd. A few S. norvegica were taken between 

 Selker Lightship and Bahama Bank on February 18th. 

 Macromysis (Praunus) inermis was taken in Red Wharf 

 Bay on December 5th, after sunset. A few specimens of 

 Macropsis slabberi were taken in a surface haul near 

 Duddon Buoy on February 24th. This appears to be the 

 first record of this species from this coast. 



Decapoda. — Decapod larvae were extremely abun- 

 dant in Carnarvon Bay and Cardigan Bay from July 

 until October. Many of these have not yet been 

 identified, but the following may be noted. 



The larvae of Pandalus montagui and Pandalina 

 brevirostris, in various stages, were common. The larva 

 of Pandalus bonnieri was taken in Carnarvon Bay on 

 July 3rd. Hippolyte varians occurred only once, the 

 first post-larval stage being taken near Causeway Buoy 

 on July 4th. The larvae of Crangon vulgaris occurred 

 in many gatherings, but never in large numbers. The 

 larvae of a species of Leander occurred in small numbers 

 at three or four Stations in Cardigan Bay- I am inclined 

 to identify these as Leander adspersus, as they agree very 

 closely with Mortensen's description. If this is correct, 

 this species must be more common in our waters than 

 had previously been supposed. 



One " Phyllosoma" was taken at Causeway Buoy
