HAYNES:PANI)A1,11)AK. HIl'I'OI.VTIDAE.ANDCRANCONIDAKLAKVAE 



Stapes II, IV-VII, from plankton; tentatively iden- 

 tified as GlyphocrangoH sp. by Kuratii (19641)); 

 figures 103-130 in Kurata (1964b). 



Stages II and IV; Makarov (1967) based identity 

 on known distribution of adults and morphology 

 of embryo of Glyphocrangon granulofsLs (see 

 Bate 1888); figure 28 in Makarov (1967). 



Most spinose of crangonid larvae known from 

 northern North Pacific Ocean (Fig. 10). Length: 

 Stage II, 5 mm; Stage VII, 13.8 mm. Range: Sea of 

 Japan; Okhotsk Sea; Port Etches, AK, to La Jolla, 

 CA; depth, 7-201 m (Butler 1980). 



Genus Sabinea J. C. Ross 



Probably 4 larval stages. In all described stages, 

 telson relatively wide, with shallow indentation; 

 pereopods 2-5 without exopodites. 



Sahinea septemcarinata (Sabine) 



Probably 4 larval stages. 



Prezoeal telson and Stages I and III, probably 

 known parentage; Atlantic specimens: plate V, 

 figures 1-23, and plate VI, figures 1-13, in Sars 

 (1890). 



Stages I and III, probably known parentage; de- 

 scribed as Crangon septemcarinatus by William- 

 son (1915); figures 167-172 in Williamson 

 (1915). Williamson's figures from Sars (1890). 



Stages I and III, from plankton; figure 12, "last 

 stage" (= Stage III), in Birshteyn (1938). 



Stage I (whole larva) and Stage III (telson); origin 

 of specimens not given; figures 1 and 2 in 

 Williamson (1960). 



Stages and origin of specimens not given, de- 

 scribed as Myto gaimnrdi by Birshteyn (1938); 

 plate 7, figure 1 (Kr0yer 1846 in Birshteyn 

 1938). 



In all described stages, anteroventral margin of 

 carapace with about 7 denticles. Abdominal somites 

 1-4 with 1, 2, 1, and 1 ventral spines, respectively; 

 abdominal somite 5 with posterolateral spine. Telson 

 with 16-1-16 setae in Stage 1, 13 -i- 13 setae in Stage 

 III. Length: Stages I-III, 7.7-11.5 mm. Range 

 area of Iceland and Faroe Islands (Williamson 1960) 

 Barents and Norwegian Seas (Williamson 1960) 

 Chukchi Sea (Birshteyn 1938); eastern coast of 

 North America from mouth of St. Lawrence River to 

 Massachusetts Bay; Arctic Ocean to Point Barrow 

 (Alaska), White Sea, and northern Europe (Williams 

 1974); depth, 10-240 m (Williams 1974).

Genus Sclerocrangon G. O. Sars 



Not more than 2 larval stages. Appendages resem- 

 ble adult except uropods enclosed and pleopods not 

 fully setose. Pereopods without exopodites; 

 pereopods 4 and 5 have characteristic sickle-shaped 

 dactyli(Fig. 11). 



Sclerocrangon horeas (Phipps) 



Two larval stages. 



Late embryo extracted from egg; plate VI, figures 

 14-28, in Sars (1890, as cited in Williamson 

 1960). 



Stage not specified, known parentage (Makarov 

 1967). No figures. 



Stage I and Stage II ("postlarval"), known parent- 

 age; figures 1-3 in Makarov (1968).
