 165, 166, 167, 168, 169, 170, 172, 173, 174, 176, 178, 179, 180, 181, 182, 

 183, 184, 185, 187. 188, 189, 190, 191, 192, 193, 203, 205, 207, 209, 210, 

 208, 212, 213, 214, 215, 216, 217, 218, 220, 223, 224, 225, 227, 229, 230, 

 231, 232, 233, 234, 235, 237, 239, 241, 242, 243, 245, 246, 247, 248, 250, 

 254, 255, 256, 257, 258, 260, 261, 262, 265, and 266. 



Of these, all numbers above 202 are very fragmentary and of little 

 value. In none of these is there any trace of the small scutes at the ends 

 of the interhsemal bones mentioned and figured by Dr. Woodward. 



This species agrees in many respects with the two fragmentary speci- 

 mens from Ilheos. named Scombrodupea scutata by Dr. Woodward. But 

 in none of our specimens, although fairly perfect, do we find any trace of 

 the little scales or scutes at the tip of each interspinal bone behind the 

 anal iin figured by Dr. W'oodward and considered by him to be the bases 

 of finlets nor do we find any trace of ventral scutes, and there could 

 have been none of these in life. Moreover, Scombrodupea scutata has 40 

 vertebrae instead of about 30, as in D. crandalli. 



It is evident that our species cannot belong to Scombrodupea, as in that 

 genus finlets are present behind the anal fin, and the ventral ridge is armed 

 with strong plates, as in Diplomystus. The genus Halecopsis seems nearer 

 to our specimens, but the character of the enlarged preopercle, which 

 defines Halecopsis, cannot be verified on any of them. In Woodward's 

 scheme, they might be referable to Clupea, but none of the fossil fishes 

 called Clupea are congeneric with the Common Herring, Clupea harengus. 

 Among other points of difference, Clupea has over 50 vertebrEe, and no 

 Tertiary or Cretaceous fish with 30 vertebrae belongs in the same genus 

 as the common living herring. 



If the detached ventral ridge scale figured by Woodward really came 

 from the specimen on which it lies, his species, scutata, may be really 

 a Scombrodupea, in which case our species is unquestionably dift'erent. 



This species is named for Mr. Roderic Crandall, of Stanford University, 

 assistant to Dr. Branner on this expedition, and now geologist to the 

 Geological Survey of Brazil. 



Family CHIROCENTRID^. 

 4. Chiromystus alagoensis Jordan, (sp. no v.) 

 In the collection are several fragments of a large fish, about a foot long, 

 apparently be'onging to the genus Chiromystus, figured by Allport (with- 

 out name) and later described by Cope and by Woodward from the Upper 

 Cretaceous at Bahia.
