 Distribution. The A/, pygniu-iis G. O. vS. was originally captured by Nans en (78'' N. 13-6° E.) 

 in considerable numbers north of the New Siberian Islands in October 1893; b\- Bruce it was taken 

 at Novaya Zemlya '^/.s 1900 and by Schaudin at Spitsbergen 8i°32 L. N. The nu)st important con- 

 tribution to it.*; distribution in the polar seas and to its biology has been published by I) a mas and 

 Koefoed in the "Due d'Orleans". It has been taken at almost all the stations in the polar seas be- 

 tween Spitsbergen and Greenland as far east as io°42 Eong. East and as far west as r8'22 Eong. \\'est, 

 as far north as 80^17 Eat. North and as far south as 75°35 Eat. North between -",',_, and '"/g 1905. The 

 authors write (p. 396) '■'■Microca/aiiiis pygii/tcus possede une grande amplitude \'erticale: il s'observe en- 

 core en abondance entre i-8oo et 1-200 metres (St. 17) et ne manque dans aucun des echantillons pro- 

 fondes. II remont frequemment a la surface. Nos peches prouvent que son niveau habituel est an 

 dessous de 100 metres". x'\s all the information about each species, which is fomid under the gatherings 

 for each station, has not been collected for each species, I have tried to do it for Aficrocalaiiiis pyg- 

 nuTus. Near the surface it has only been found: at St. 13 (0—20 meLres, T. 0-30° C, vSalin. 33-30700, 7? 

 4-45 p. m.), at St. 30 (0-5 metres, T. 1-20" C, Sal. 31-32700 '7/ ^ p. m.) ami at St. 43 (0—20 met. T. 0-98° 



=- 1-64° C. Sal. 32700 '/s 3 p. m.). As the salinity at which this S]jecics has been fountl lies between 



31-10 7oo and 35 7oo the said authors may be right (p. 406) in referring it to the intermediary group of 

 species, which in the Norwegian Sea exceptioualh' are observed "a la surface surtoul pendant la unit 

 et dans les endroits, ou la salinitc est elevee"; but their final statement, indicating a difference in the 

 vertical distribution in the different seas, about M. pygiiicrtis (p. 407) "a) Dans la Bassin polaire: con- 

 state a de faibles profundenrs. b) Dans la RIer du t^ronland: priucipalemeut vers 100 metres; existe 

 depuis la surface ju,sque a 1850 metres, c) Dans la Mer de Norvegc: .sourtout abondant entre 200 et 

 600 metres", is neither born out by their own nuiterial (tab. II) nor by the information available in 

 the literature. The species has not \et been recorded from the Norwegian Sea. The temperature, at 

 which this species has been found even in great numbers (cc) at different depth.s, vaiies from -h- 1-75 

 to +2-i5°C.; it has been found fairly common ( | ) at 3-81" C, but its oplinmms temperature seems 

 to be a little below and a little above Zero. AdiUt males have been found at 11 stations in the Green- 

 laud Sea between 'V, ^^'i^^^ '';'^' '" vertical hauls from 60 to 20 and from kkxi to 800 metres and at
