the abdominal cavity. From what was observed, it appears that 

 these spines grew longer as the csecal cavity grew less, towards 

 the distal end of the fish. 



The Regalecus appears to be rather a rare fish everywhere, 

 its first recorded occurrence in Britain being in the 'Annual 

 Register^ of 1759. Since that time some eleven or twelve spe- 

 cimens have been observed, all on the north-east coast. Its first 

 recorded occurrence in Scotland was of a specimen stranded at 

 the village of Crovie, in Banfi*shire, in 1844. Another was 

 stranded in the Bay of Cromarty in 1852. The St. Andrews 

 fish, in 1861, makes the third time it has been noticed on the 

 Scottish coast.

 By Joseph S. Baly. 



Genus Lema, Fab. 



Lema frontalis, 



L. anguste oblonga, subcylindrica, nitida, testacea, pectore antice 

 abdomineque piceis ; capita (fronte excepto) nigro ; antennis sub- 

 filiformibus, articulo ultimo basi fulvo-albo ; thorace transverse, 

 subcylindrico, lateribus medio modice constrictis, dorso ante basin 

 trans versim sulcato, hie ilHc fortiter punctate, medio utrinque 

 unifeveelate ; eljtris viridi-cyaneis, basi vix elevatis, infra basin 

 transversim depressis, sat profunda striate-punctatis, interspatiis 

 laevibus, remote punctatis, ad apicem subelevatis ; tibiis extrorsum 

 tarsisqua fuscis. 



Long. 2-2i lin. 



Hab. Lizard Islands, Northern Australia. 



Narrowly oblong, subcylindrical, nitidous, testaceous; ante- 

 rior part of breast and the abdomen piceous ; elytra cyaneous ; 

 apical half of tibia, together with the tarsi, nigro-piceous. Head 

 black, with the exception of a large oblong rufous patch on the 

 forehead ; face triangular, its lower portion slightly produced ; 

 epistome separated from the face by a deep groove, from the 

 apex of which an oblique sulcation runs upwards on either side 

 along the edge of the orbits ; upper portion efface coarsely punc- 

 tured, bilobed ; antennae modei*ately robust, subfiliform, basal half 

 of apical joint obscure white. Thorax transverse, sides mode- 

 rately constricted in the middle, the upper surface deeply im- 

 pressed in front of the base with a transverse sulcation, which 

 extends at either end into the lateral constriction, its middle im- 

 pressed with a single deep fovea ; surface of disk coarsely punc- 

 tured on the sides in front and down the middle, the latter 

 part impressed on either side by a large deep fovea. Scutellum
